Introduction
Tourism is a major economic sector that has experienced unprecedented growth in recent decades.However, this growth has also led to negative impacts on the environment, culture, and society in many destinations.Overtourism, which refers to the situation where the number of tourists exceeds the carrying capacity of a destination, has become a pressing issue in many parts of the world [1].The COVID-19 pandemic has affected and changed consumers' behaviour [2], minimising the problem as temporary restrictions and health concerns have reduced tourist flows to some destinations while exposing the vulnerabilities of tourism-dependent economies [3].In this context, new digital technologies and the metaverse have emerged as potential solutions to address the challenges of overtourism and create new opportunities for destinations [4,5].The metaverse and new digital technologies are here to stay and to change from the ground up the way we think, experience, remember, and share our vacations and trips [6].New technologies that are used a lot in gaming right now will most probably be used soon in other fields, like tourism.
The focus of this paper is on investigating how digital transformation can be used by the tourism industry to address overtourism vulnerability and promote destination sustainability.In particular, the article will examine the impact of the metaverse and new digital technologies on the travel and tourism industries, with a view to determining their potential for mitigating destinations' overtourism vulnerability.This article responds to the following research question (RQ): How and what kind of digital technologies address overtourism issues?
By addressing this research question, the article aims to provide valuable insights into how destinations can leverage digital tools and technologies to manage tourist flows more effectively while promoting sustainable tourism practices.It is proposed that destination management could use some of the new emerging technologies to ease the burden of overtourism for the world's most popular (or most overexploited) destinations, promoting their sustainability, preservation, and long-term viability.The paper's contribution is to provide an analysis of the existing literature on tourism-related aspects of the metaverse and new digital technologies that could correlate with overtourism.Consequently, some of the various digital tools, methods, and technologies that can be applied to address overtourism are discussed, and their applications and opportunities for destinations are portrayed.

Theoretical Background 2.1. Overtourism Phenomenon
As demonstrated by various studies [7][8][9], overtourism is a pressing issue that has detrimental effects on both the environment and local communities.When destinations become too popular and exceed their carrying capacity, it can lead to overcrowding, cultural commodification, and social and economic imbalances [10][11][12].To combat the negative consequences of overtourism, sustainable tourism practices must be implemented to ensure that destinations can accommodate visitors in a responsible manner [8].Overtourism has emerged as a significant debate issue in many well-known tourist destinations around the world in recent years.The results of a study by the activist travel company Responsible Travel indicate that 98 locations spread across 63 countries are struggling because of high visitor numbers [13].
One trend that has emerged in the literature regarding overtourism is the need for a more nuanced understanding of overtourism.Scholars have argued that overtourism is a complex and multifaceted phenomenon that cannot simply be reduced to issues of overcrowding and environmental degradation [10][11][12].The impacts of overtourism can be even more wide-ranging and can include damage to cultural heritage sites, depletion of natural resources, commodification of culture, deterioration of the built environment, and social and economic imbalances [7,8,10,14].Researchers have identified several key factors that contribute to overtourism, including the growth of low-cost air travel, the rise of online booking platforms, the "touristification of housing", and the increasing popularity of sharing economy services [14][15][16][17].It is therefore crucial that academics and practitioners adopt a more holistic approach to understanding the various social, economic, and cultural factors that contribute to the phenomenon of overtourism.
Another trend that has emerged in the literature is the importance of community involvement in addressing overtourism.Scholars have argued that local communities have a critical role to play in addressing overtourism, since they are often the most directly impacted by the negative consequences of mass tourism [8,16,18,19].Therefore, it is essential that tourism planners and policymakers engage with local communities to develop solutions that are mutually beneficial and sustainable [19,20].
Finally, an emerging trend in the literature is the need for more innovative and sustainable tourism practices.Scholars have argued that traditional tourism models based on mass tourism and high-volume, low-value tourism are not sustainable in the long term [21][22][23].In this regard, some destinations have implemented measures to limit the number of tourists, while others have focused on promoting ecotourism, responsible tourism, cultural tourism, and community-based tourism [14,16,24,25].All these efforts are aimed at ensuring that tourism is managed in a way that benefits both tourists and local communities while being environmentally and socially sustainable.Additionally, these models embrace principles of sustainability and are more aligned with the values of contemporary tourists who seek authentic, meaningful, and sustainable travel experiences [26,27].

Destination Management
Destination management has been an important subject in the field of tourism studies, and there have been a number of noteworthy trends in the literature over the past few years.
One trend that has emerged is the importance of destination governance for effective destination management.Scholars have argued that collaborative governance structures that involve local people and stakeholders from multiple sectors and levels of government are critical for sustainable destination management [11,12,21,22].Another trend in the literature is the need for destination management to be grounded in a solid understanding of the destination's unique characteristics and competitive advantages [22,23,27].This requires a thorough analysis of the destination's resources, attractions, and visitor profiles, as well as a strategic approach to product and service development.
Finally, there has been an increasing emphasis on the role of technology in destination management.In order to succeed in the new digital era, destinations will need to comprehend their visitors' preferences and sustainably offer them an interconnected and seamless brand experience [6].This includes the use of data analytics, artificial intelligence, blockchain, and digital platforms to enhance visitor experiences, improve destination marketing, and monitor and mitigate visitor impacts.Scholars have pointed out that these technologies are expected to cause significant changes in how tourism is experienced as well as how destinations are managed [28][29][30].Destination managers should also be open to embracing these technologies in order to remain competitive in the industry [30].In fact, Buhalis [30] suggests that the use of such technologies will become a determining factor for competitiveness within the tourism ecosystem.However, scholars caution that technology should be used in ways that are compatible with the destination's cultural and environmental values and should not undermine the authenticity of the destination experience and the human touch [25][26][27].Additionally, it is crucial to ensure that these technologies do not exacerbate existing inequalities and are accessible to all.

Metaverse Environment
The metaverse is a concept that has gained significant attention in recent years.It refers to a virtual shared space that is created by the convergence of various physical and virtual environments [31,32].This environment allows users to interact with each other and with computer-generated elements in real-time [32].With the help of augmented and virtual reality technologies, the metaverse can expand the physical world and allow people to interact naturally using avatars and holograms [30].It is an exciting area of research that has the potential to revolutionise how people interact with each other and their surroundings.
The emergence of the metaverse is a result of the convergence of technological advancements and societal changes [33].As highlighted by Dwivedi [30], the COVID-19 pandemic has accelerated this trend, leading to increased interest from investors and speculation that the metaverse may be the next frontier in internet development.As such, it is crucial to understand the potential implications and opportunities that arise from this phenomenon.
The transition from the current Internet to the metaverse is being driven by several enabling technologies, including artificial intelligence, blockchain, computer vision, IoT and robotics, edge and cloud computing, user interactivity, and immersive technologies such as virtual reality and augmented reality [32][33][34][35].These technologies are currently being used in various digital activities that offer insights into user expectations and emergent metaverses [34][35][36].For instance, platforms such as TikTok, Google Arts & Cultures, Twitch, and Minecraft provide mixed reality settings that can be compared to those found in metaverses [36].
The metaverse, the "post-reality universe" that is expected to reach maturity in 2030, holds significant potential for transforming the way individuals and brands interact with each other [32,36].According to Gartner [37], by 2026, a quarter of people will spend at least an hour per day in the metaverse, engaging in a range of activities such as work, shopping, education, entertainment, and socialising.This suggests that the metaverse is poised to become a major force in shaping the future of human experiences across various domains.Further research is needed to explore how tourism and different industries can leverage this new platform to enhance their operations and engage with consumers in novel ways.

Tourism-Related Digital Tools and Technologies
To combat the negative effects of overtourism, the tourism industry is crucial to recognise the significance of adopting new technologies, tools, and applications [28,30,38,39].By keeping abreast of these developments, the tourism sector can provide personalised and sustainable customer experiences while simultaneously contributing to a stronger and more sustainable industry, mitigating the burden of overtourism [6,20,[40][41][42].The tools and technologies that could be utilised in this direction, and are strongly associated to metaverse, are listed below.[43][44][45].XR technologies include virtual reality (VR), augmented reality (AR), and mixed reality (MR).VR is a technology that creates a completely simulated environment that replaces the real world, whereas AR overlays virtual objects onto the real-world environment.MR is a combination of VR and AR, allowing the user to interact with both the virtual and real-world environments simultaneously [40,[43][44][45].These technologies have been used in a variety of industries, including tourism, entertainment, education, healthcare, and retail, since they have proven to be effective in enhancing learning experiences, improving productivity, and providing unique marketing opportunities [40,[43][44][45][46][47][48][49][50].As XR technologies continue to advance, their potential to revolutionize the way we interact with the world around us is becoming increasingly apparent.
The rapid development of XR technologies has the potential to revolutionise tourism by offering visitors immersive and interactive experiences while they are not physically present in the same location [48,49].Several research findings [6,34,35,40,51] suggest that augmented reality (AR) has the potential to revolutionise the tourism industry by enhancing visitor experiences with immersive and stimulating content.By incorporating cutting-edge technologies such as virtual reality and augmented reality, it may be possible to offer tourists an alternative way to explore destinations without negatively impacting local communities or depleting natural resources [27,40,52].
In fact, with the increasing accessibility of AR on mobile devices, smart destinations are utilising this technology to enhance sustainability [53], while at the same time creating new visitor experiences and building communities in the metaverse era [52].VR and AR technologies have allowed destinations to create engaging and interactive experiences that were previously impossible [40,54].This could not only lead to a more memorable travel experience but also help alleviate issues such as overtourism in popular destinations during peak periods.As such, it is likely that we will see continued growth in the use of immersive technologies in the tourism industry in the coming years.
A study by Hopf et al. [55] explored the potential of virtual reality (VR) and augmented reality (AR) technologies to offer immersive and sustainable tourism experiences.The study suggested that these technologies could be used to create virtual replicas of destinations, allowing tourists to experience a destination without physically visiting it and, in this way, reducing the tourist crowds visiting them [55].
It is clear that the integration of XR technologies into cultural sites, such as museums and cathedrals, has a significant impact on the preservation and accessibility of historical artefacts [25,45,[56][57][58][59], which are challenged by overtourism.These immersive technologies provide a means for individuals to explore and experience these sites from anywhere in the world, creating a virtual reality that is indistinguishable from reality [45,54,54].In addition to physical restoration, the use of XR can enhance visitors' experiences by enabling them to access previously inaccessible areas and providing a profound sense of presence within historical structures [56,58].As such, it is evident that these technologies have the potential to revolutionise the way we approach cultural preservation and visitor engagement at heritage sites, promoting their sustainability [25,45].

Artificial Intelligence (AI)
The use of AI in destination management will not only benefit the tourism industry but also have a positive impact on the environment [60].By analysing data on tourist behaviour and preferences, destinations can make informed decisions about resource management and reduce their carbon footprint [21,61].
For example, they can identify peak periods of tourist activity and adjust their energy consumption accordingly.Additionally, AI-powered systems can help with waste management and water conservation, leading to a more sustainable tourism industry in the metaverse.As destinations become more conscious of their environmental impact, they will be able to attract eco-conscious travellers who are increasingly seeking sustainable tourism experiences [24].
Through the use of AI, destination managers could be able to effectively analyse large amounts of data to gain insights into tourist behaviour, traffic patterns, preferences, and environmental impacts [18,21,58].This will allow destinations to identify vulnerable areas and create targeted strategies for sustainable tourism.Additionally, destinations could create more personalised experiences for visitors, who will "engage in a dynamic co-creation of experiences within the tourism business ecosystem" [30].
By utilising this data, destinations could also target specific parts of the market with their marketing efforts, ultimately leading to a more successful and sustainable tourism industry.

Digital Twins
Digital twins are virtual replicas of physical spaces, such as cities, buildings, and landmarks [62].In tourism, they are being used to create virtual tourism experiences that allow visitors to explore destinations before they visit in person, while additionally aiding in the preservation of historical sites and landmarks by creating their accurate digital replicas [38].
Frey [57] proposed the replication of heavily visited historical sites in nearby locations, enhanced with the use of advanced digital technologies such as holograms and digital twins, to make these cultural sites more appealing to tourists from all backgrounds.This approach not only helps to distribute the tourist flow and reduce overcrowding, but it also provides visitors with a more immersive and interactive experience.By incorporating cutting-edge technologies, tourists can engage with historical sites, events, and cultural practices in a more engaging and informative way [58,63].
This approach has already been successfully implemented in many famous museums around the world, such as the British Museum in London, the Pergamon Museum in Berlin, the Guggenheim Museum in New York, and the Hermitage Museum in St. Petersburg, among others.In addition, in China's Forbidden City, visitors can explore the ancient palace through a virtual reality experience, whereas Dubai has also created a digital twin of the city that allows visitors to explore its landmarks and attractions virtually.
The technology not only provides a preview of the destination but also helps in efficiently planning the trip [64].As cultural tourism continues to grow in popularity, it is essential to explore innovative solutions that balance the needs of visitors with the preservation of cultural heritage sites [25,38].

Blockchain
Another technology that can help address overtourism is blockchain.It could offer a decentralised and secure communication system that facilitates direct interactions between tourists and local communities as well as transparent record-keeping of tourism transactions [21,38,41].Blockchain can provide a framework for sustainable tourism by allowing tourists to engage directly with local communities and tourism providers while ensuring that all parties' benefits are properly documented [41].
Blockchain technology is being used to create decentralised tourism platforms that allow tourists to book travel services and experiences directly from local providers.These platforms can help promote more sustainable tourism practices [41] while also controlling visitor numbers and avoiding overtourism.Decentralised platforms could also provide a more authentic and personalised travel experience by connecting tourists with local hosts and promoting community-based tourism [18,23].

Internet of Things (IoT)
The Internet of Things is another technology that is likely to impact destination management.By connecting devices and sensors, the IoT can help destination managers monitor and optimise the use of resources such as energy and water [21,61,65].It can also be used to create smart tourism experiences such as interactive exhibits, augmented reality tours, and virtual reality experiences [60,61,66].The European Commission [67] highlighted the need for updated digital infrastructure as destinations "provide digitally enhanced tourism services and implement more digital business processes, or consider developing digital tourism services".This way, the targeted digital transformation of the tourism sector will move across the metaverse and unite destinations, businesses, and customers with digital experiences, services, and business processes in a seamless way.The integration of the internet of things and smart technologies in the tourism sector could be a valuable asset, offering innovative and sustainable solutions for efficient and effective management that can potentially address overtourism challenges [68].With the emergence of smart applications, services, and management techniques, there is great potential for the IoT to transform the way we approach evidence-based practice in tourism management [61].
IoT, together with blockchain, can assist in the management of tourist flows, enabling destination managers to better understand and predict patterns of movement and congestion.This information can be used to improve infrastructure and services, reducing the impact of tourism on local communities and the environment.Digitalization tools are already helping destinations improve their brand loyalty and engagement, as "smart tourism technologies and memorable tourism experiences play essential roles in enhancing tourist satisfaction and destination loyalty" [69].The integration of these technologies has the potential to revolutionise the way we manage tourism, creating a more sustainable, overtourism-free, and enjoyable experience for both tourists and locals alike [27,64].
In conclusion, these tools and technologies have the potential to mitigate the negative impacts of overtourism by providing data-driven insights into tourist behaviour, facilitating stronger relationships between tourists and local communities, and creating immersive experiences.The adoption of these innovations can pave the way for a more sustainable future for the global tourism industry.However, it is important to ensure that the use of digital technologies does not completely replace physical tourism and negatively impact local economies that rely on tourism revenue.Studies highlighted the need for careful consideration of the environmental impact of virtual tourism experiences, as they still require significant energy and resources (data, storage, computing power, etc.) to create and maintain the requested experiences [4,70].Therefore, a balance between physical and virtual tourism could be the best way to ensure sustainable tourism development.

Research Strategy
The chosen research methodology for this study is a systematic review of the existing literature, using the PRISMA statement for literature reporting.This approach allows for a comprehensive and detailed examination of the available research on a particular subject, enabling the identification of patterns, discrepancies, and gaps in existing literature through a methodical search and analysis of all relevant studies.Grant and Booth [71] argue that this method can provide a more nuanced understanding of the topic being researched.
A critical literature review paper, according to Garrod [72], is a "self-contained academic work that seeks to review the literature on a specific subject or theme using a critical-thinking approach."In the case of this paper, a systematic literature review can assist in identifying areas that require further study.By analysing the existing literature, it is possible to identify knowledge gaps and areas with contradictory findings, thereby facilitating the identification of novel and significant research questions.
The systematic literature review is a crucial research methodology that ensures thorough and transparent analysis [72,73].In order to ensure the validity and dependability of the review, Grant and Booth [71] stress the importance of adhering to a predefined protocol or plan that outlines evaluation criteria.This view is supported by Pollock and Berge [74], who assert that for an effective and exhaustive systematic review, it is essential to establish a clear protocol, identify relevant research, collect data, evaluate study quality, synthesise evidence, and interpret results.By following these essential steps, researchers can ensure that their systematic reviews are reliable and valuable contributions to their respective fields of study.
When a clear protocol is required for a systematic review, adherence to the PRISMA statement is highly recommended [75].The use of PRISMA's standardized checklist ensures that all necessary information is included, resulting in transparent and reproducible research, while also assisting in the identification of potential biases and limitations, thereby enhancing the study's quality and credibility [75][76][77].
Based on the abovementioned, through a systematic literature review, researchers can gather and analyse existing studies related to their topic of interest, identifying trends, gaps in knowledge, and potential areas for future research.This approach is particularly useful for policymakers and practitioners who require evidence-based information to inform their decision-making processes.By conducting a systematic review, they can be confident that they have considered all available evidence and have a comprehensive understanding of the current state of knowledge on their topic.Ultimately, this can help to ensure that resources are allocated effectively, leading to better outcomes for individuals and communities.

Materials
The present study is grounded in a rigorous selection of the literature that is deemed original and critical in its discussion of overtourism and new digital technologies, particularly the metaverse.Employing the systematic literature review method, the study examines recent works published between 2019 and 2023 as a means to capture the latest developments in this emerging field of tourism research.Given the growing interest in the metaverse and its potential impact on overtourism, this focus on the recent literature is particularly relevant to our research goals.

PRISMA
The PRISMA methodology, 2020 version, was used in this study.The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement (henceforth referred to as PRISMA) is a reporting guideline intended to address inadequate reporting of systematic reviews [75].The PRISMA statement includes a checklist of items recommended for reporting in systematic reviews, an "explanation and elaboration" paper that provides additional reporting guidance for each item, as well as reporting examples [75][76][77].

Eligibility Criteria
The authors decided to use the keywords "overtourism" OR "over-tourism" due to their ambiguity and wide use in the literature, excluding "over tourism" which does not refer to the subject.Additionally, AND "metaverse" OR "artificial intelligence, augmented reality, virtual reality, digital twins, digital transformation" keywords were used in order to indicate the connection to the remaining researched aspects.Moreover, the papers were limited based on their publication dates.Only the more contemporary works published between 2019 and 2023 were included in the sample.As can be seen in Table 1 below, 260 potentially selectable contributions were identified within the selected databases, complying with the set eligibility criteria.

Information Sources and Search Strategy
The following academic databases were chosen for assessment: Emerald Inside and Google Scholar.Using Boolean operators (AND, OR, NOT, or AND NOT; including brackets and quote marks) as conjunctions to include or exclude keywords in our search, a search string was constructed, resulting in more concentrated and effective results.Because of the finding that researchers do not use univocal language to describe overtourism, it became obvious that exploratory research played an essential role in determining the list of keywords.
After the selected searched records (n = 260) were exported from the Zotero tool, they were screened following the PRISMA methodology procedures described in Figure 1.Each author independently reviewed and evaluated the retrieved records.The authors then gathered and discussed the evaluation's results.Articles were included only if consensus was reached among all authors.A significant strategy for preventing a single reviewer from implementing a biased (or flawed) explanation of review criteria was implemented at this stage in order for the two independent reviewers to minimise bias at pivotal phases of the review process.This approach not only ensures the reliability and validity of the review process but also helps to minimise the risk of errors and inconsistencies; whereas, it also allows for a more comprehensive evaluation of the articles under consideration [76].

Selection Process Analysis
At this stage, the papers noted as duplicates (n = 4) were initially deleted.Continuing, the scientific papers that were not written in English (n = 5) were excluded.
After that, the remaining papers were subjected to a screening of their abstracts.In books and book chapters, the indexed contents and chapter titles were screened.This process selected only the sources that were focused on the review's research thematic and topics.As a result, were selected only the sources where the selected three (n = 3) keywords "tourism", "overtourism", and "travel" were included in the abstract, index, or chapter titles of the finally selected papers (n = 85).At this stage, one hundred and sixty-six (n = 166) papers were eliminated as not directly related to the research's thematic, subject, and objective.
A full-text screening was then performed on the remaining eight-five (n = 85) papers to confirm the existence of the aforementioned eligibility requirements related to overtourism thematic.In four (n = 4) cases, no full-text records were available, and these papers were excluded.In addition, another group of twenty-five (n = 25) papers were eliminated because, in their full texts, they did not address the overtourism thematic or overtourism-related issues and, therefore, would not have been able to answer the study's research question.Furthermore, another criterion was applied and of this only peer-reviewed articles, conference papers, white papers, and published books were chosen, and as a result, three (n = 3) additional papers were eliminated.The implementation of the above-mentioned search techniques resulted in the final selection of fifty-three (n = 53) papers (Table 1), which fulfilled the set relationship between the metaverse, new digital technologies, and overtourism-related issues.

Results
It is evident from the research literature that the metaverse presents a promising opportunity for the tourism industry to generate additional revenue streams and create new, unique experiences for tourists [4,30,63,64].By offering new and unique virtual experiences, destinations can attract a wider audience while also reducing the negative impact of physical tourism on natural resources [27,40,53].At present, the tourism industry contributes significantly to overtourism in popular destinations worldwide, often leading to overcrowding, environmental degradation, and damage to cultural heritage sites [7,8,14,78,79].The integration of these technologies into destination management plans appears to have the potential to alleviate some of the negative impacts associated with high levels of tourism in a destination [6,20,39].

Economic Aspects
The metaverse concept applied in tourism could offer tourists a virtual experience of destinations, which could create new business opportunities besides reducing the negative impacts associated with physical tourism [4,30,38,51,[80][81][82][83].This virtual experience could also offer unique opportunities for tourism businesses to showcase their products and services in a new way [38,40,82].For example, local businesses could partner with tourism boards to create virtual experiences that highlight the culture and history of their area, not only attracting more visitors but also providing an additional revenue stream.According to Go and Kang [4], licencing destinations' digital products could provide an additional revenue stream for destinations that may have been struggling due to declining physical visits.This approach has the potential to benefit both the tourism industry and the environment by offering a sustainable and innovative way for people to explore the world while also supporting local economies.
A shift towards virtual tourism experiences could also help distribute the economic benefits of tourism more evenly and allow smaller and less well-known destinations to attract visitors [23,27].For instance, Metaverse applications could be used to offer virtual tourism experiences in isolated, rural, or sensitive areas that cannot support mass tourism physically [27,40,84].This would permit visitors to discover, explore, and appreciate these areas without negatively impacting the environment or local communities.

Customer Experience Aspects
Metaverse virtual experiences could be customised to the users' preferences and interests, creating targeted and personalised recommendations that facilitate tourism without overstressing a destination [6,64].With the ability to customise experiences based on user preferences, metaverse tourism could provide targeted and personalised recommendations that encourage a more even distribution of visitors throughout the year [6,20,39,42].This approach would not only reduce the strain on popular destinations but also offer opportunities for people who are unable to travel physically or cannot afford financially to experience different parts of the world [40].
In addition, the implementation of immersive digital technologies can serve as a potent tool for destination marketing, improving the destination image and raising awareness among potential visitors [9,18,50,80].Immersive digital technologies, such as virtual reality and augmented reality, can offer visitors a unique and engaging experience of the destination before they arrive [30,40,58].This not only helps to attract more visitors, but it also enhances the overall customer experience by enabling visitors to make informed travel decisions.By combining tourism practices with cutting-edge digital technologies, destinations can provide tourists with a more comprehensive and enjoyable experience [38].
The use of the metaverse and its associated technologies could offer tourists an opportunity to experience and engage with destinations in a sustainable and controlled manner that could mitigate overtourism phenomena [4,6].However, it is important to ensure that these technologies are accessible and inclusive for all tourists to experience them.It is vital to consider the potential digital divide that may exist within a destination, as not all residents and tourists may have equal access to or familiarity with the new technologies [17,40,65].Therefore, efforts should be made to ensure that these technologies are accessible and user-friendly for all stakeholders, so that all visitors have the same level of customer experience and satisfaction.
Additionally, the use of digital technologies can facilitate better communication and collaboration between tourists, residents, and local authorities, resulting in more effective management strategies towards sustainable tourism [11,16,85], which could in its turn address overtourism and have as a result a better customer experience for destination visitors.

Sustainability Aspects
By enabling stakeholders to monitor and mitigate the environmental impact of tourism activities, immersive technologies can also aid in the development of sustainable tourism practices [28,39,40].This can help ensure that tourism remains a viable and sustainable industry for years to come.The integration of immersive digital technologies (like AR and VR) into the tourism industry could offer immense potential for destination managers to gain valuable insights into tourists' preferences and behaviours [7,14,24,28].The utilisation of these technologies can inform decision-making processes, leading to improved sustainability practices that could address overtourism and enhance visitor experiences.
Metaverse and the related digital tools and technologies can reduce the physical movement of people, limit the impact of tourism on the environment and cultural heritage sites, and even mitigate the spread of diseases, as it is becoming increasingly challenging to manage tourism in a post-COVID-19 world [3,20,25].However, it is essential to identify different best practices for implementing these technologies in different environments and view them as one of many sustainable tourism strategies in the context of strategic destination management planning [18,21,24,86].By leveraging the power of digital technologies, it is possible to create a more sustainable and responsible tourism industry that will address the overtourism issue and benefits both tourists and local communities alike.

Considerations
Incorporating digital technologies into the tourism industry carries with it both potential benefits and obstacles, which must be acknowledged.While the metaverse offers opportunities for locals to showcase their culture and heritage in a sustainable way [23,25,58,87], it is also important to preserve the quality and authentic travel experiences [84,86].Scholars [12,18,19,88] stress the significance of involving the local community in planning and management activities to ensure that digital technologies are aligned with the needs and values of the destination.To achieve this balance, thorough research and consultation with local communities must be conducted to ensure that the use of technology aligns with their cultural values and beliefs [23,65,84].It is crucial for the tourism industry to adapt to this new dynamic environment and re-position itself accordingly [6,30] in order to create a more sustainable and responsible sector.
Virtual experiences could not fully replace the authenticity of actually visiting a destination [40,55] and, therefore, if used detached from other actions, would probably not be a sufficient solution to overtourism, as they do not address the root cause of the problem [1,7,10,12,18,24,39,85,89].The success of implementing these new technologies depends on various factors, such as the destination context, the level of stakeholder engagement, and the type of technology employed [11,16,40,41,57,64,82,85]. Therefore, it is imperative to carefully evaluate the potential impacts and limitations before deciding on the adoption of these technologies to ensure their successful integration into the destination's tourism industry and minimise any negative consequences that may arise.This can be achieved through conducting thorough feasibility studies and involving all relevant stakeholders in the decision-making process [7,11,12,16,85].
The metaverse related digital technologies could have potential negative effects, such as the displacement of local communities and the erosion of cultural authenticity [19,22,27].Despite the optimism surrounding their possibilities for addressing overtourism, it is unclear whether metaverse tourism will potentially completely substitute physical travel or function only as a supplementary option for travellers [40,90].
It is essential to ensure that the metaverse and virtual tourism do not completely replace physical travel, as this could have negative impacts on local economies that rely heavily on tourism.Furthermore, the technology and infrastructure required for metaverse tourism could be costly and require significant investment, which may not be viable for all destinations, especially those located in less developed regions [51].
Given these uncertainties, additional research and analysis are necessary to fully comprehend the implications of this emerging trend.
In conclusion, the metaverse and its associated emerging technologies have the potential to mitigate overtourism at destinations, but in order to ensure their successful integration and minimise any negative consequences, it is crucial to conduct thorough feasibility studies and involve all relevant stakeholders in the decision-making process.The existence of a digital divide within a destination should be taken into account, and measures should be taken to make it accessible to all parties involved.Despite the fact that these innovations have the potential to tackle the issue of overtourism, more study is required to determine optimal deployment strategies and assess their effectiveness in various settings.It is important to view these technologies as one tool among many sustainable tourism strategies and continue to assess their potential impact on destinations and stakeholders.

Findings
The research question addressed by this paper is: how and what kind of digital technologies address overtourism issues?
Based on the findings, the metaverse and its associated digital technologies have the potential to assist in the campaign against overtourism in popular tourist destinations by providing virtual experiences that decrease the physical impact of tourism.Virtual experiences can provide visitors with a taste of a destination without requiring them to physically travel there, thereby reducing the tourism industry's footprint.
Metaverse technologies could facilitate tourists' experiences of destinations without physically visiting them, thereby reducing the strain on local infrastructure and reducing the number of tourists.Furthermore, technology such as the metaverse has the potential to support sustainable tourism practices by enabling local stakeholders to monitor and mitigate environmental impacts.With careful consideration and planning, the metaverse and virtual experiences can offer promising solutions for sustainable development in the tourism industry.
Moreover, the metaverse can provide residents with opportunities to sustainably exhibit their culture and heritage.This can also lead to increased awareness and appreciation of diverse cultures, as well as provide economic benefits for local communities through virtual tourism.However, it is important to ensure that virtual experiences are used in a complementary way to enhance the overall tourism experience.Additionally, virtual experiences can offer accessibility to individuals with physical disabilities or financial limitations who may not have been able to travel otherwise.
However, it is crucial to ensure that virtual tourism does not entirely replace physical travel, as this could negatively affect local economies that rely heavily on tourism.While the metaverse and virtual experiences offer promising solutions to overtourism, they should be viewed as complementary rather than a substitute for physical travel.In this way, virtual tourism can support sustainable development while also promoting economic growth in local communities.
The success of implementing these new technologies is contingent on a number of variables, including the destination context, the level of stakeholder engagement, and the employed technology.Before deciding to adopt these technologies, it is essential to evaluate their potential impacts and limitations in order to ensure their successful integration into the destination's tourism industry and minimise any potential negative consequences.
It is also essential to be aware of the potential negative consequences of implementing the metaverse's digital tools and technologies, such as the displacement of local communities and the erosion of cultural authenticity.Promoting responsible tourism practices that aid local small and medium companies and offer job opportunities to locals can help achieve this.As a rule, a destination's tourism industry needs to be integrated successfully into the community in a way that promotes local prosperity, environmental preservation, and social cohesion.
While metaverse tourism could be a solution to the problem of overtourism, it is not yet known whether the necessary technology and infrastructure can be afforded by all destinations, especially those in less developed regions, due to their high costs and high investment requirements.
Overall, the integration of digital technologies into the tourism industry can contribute to a more responsible and sustainable industry, but it is essential to establish a balance between leveraging these technologies, preserving authentic travel experiences and including all stakeholders in the decision-making process.Scholars stress the significance of involving the local community in planning and management activities to ensure that digital technologies are aligned with the requirements and values of the destination.This paper's findings suggest that the utilisation of the metaverse and its associated tools and technologies could be a promising solution to the issue of overtourism if accompanied by the planning and implementation of a coherent destination strategy towards sustainable tourism.The metaverse has been identified as a potential sustainable alternative to physical tourism, which is particularly relevant in light of issues surrounding overtourism.Nevertheless, the success of the metaverse as a tourism mode will depend on a range of factors including destination management policies, local regulations, technological infrastructure, and stakeholder engagement.New technologies have the potential to mitigate overtourism at destinations, but it is essential to undertake exhaustive feasibility studies and involve all relevant stakeholders in decision-making.In addition, it is essential to consider the possibility of a digital divide within a destination and to make efforts to ensure accessibility for all stakeholders.In addition, more research is necessary to identify best practices for their implementation and evaluate their efficacy in a variety of contexts, as it is essential to view these technologies as one of many sustainable tourism strategies and to continue evaluating their impact on destinations and stakeholders.Research into the advantages, disadvantages, and potential solutions to this ever-changing landscape is essential before it can become a dominant form of tourism.
