Spain has emerged as the strongest performer in a new cross-European analysis of potentially AI-generated or AI-enhanced hotel photographs, recording the lowest proportion of flagged images among destinations examined in Italy, Germany, Turkey and Greece.
The privately commissioned study analysed 25,550 hotel photographs from 700 randomly selected properties across Mallorca, Sicily, Usedom, Alanya, Crete, Berlin and Hamburg. Researchers reported that 4,778 images, equivalent to 19 percent of the sample, displayed at least one technical or visual indicator commonly associated with artificial intelligence.
However, the findings do not prove that every flagged photograph was generated by AI or used to deceive travellers. The methodology grouped fully generated imagery together with conventional photographs that may have undergone AI-assisted enhancement, making careful interpretation essential.
Mallorca recorded the lowest suspected share at 9 percent, with 360 of 4,014 images flagged. Sicily followed at 11 percent, Usedom at 12 percent and Alanya at 13 percent.
Crete reached 23 percent, while Berlin recorded 27 percent. Hamburg produced the highest proportion, with 1,191 of 3,285 analysed images, or 36 percent, showing at least one suspected AI-related characteristic.
Mallorca Records Lowest Flagged Image Rate
Mallorca’s result places the Spanish destination ahead of the other tourism markets included in the analysis, particularly the major German cities where suspected AI involvement was substantially higher.
The findings are especially relevant for Mediterranean destinations because accommodation photographs strongly influence holiday bookings. Travellers often compare beaches, swimming pools, guestrooms, restaurants and resort surroundings before reading detailed descriptions or examining property policies.
A visually enhanced image can therefore influence perceptions of space, quality and value before a reservation is completed.
AI tools can now brighten skies, improve landscaping, remove imperfections, sharpen interiors and adjust lighting far more quickly than traditional editing software. They can also alter proportions, reconstruct missing details and generate scenes that may not accurately reflect everyday conditions.
The central issue is not routine image correction but whether technology materially changes what a guest can expect to find after arrival.
Private Study Raises Questions, Not Final Conclusions
The May 2026 analysis was conducted by Berlin-based marketing agency ABCD Agency with forensic AI verification provider ContentGuard.me.
Researchers examined hotel imagery covering accommodation, dining areas, pools, wellness facilities and outdoor spaces. They assessed metadata, pixel structures, rendering patterns and other signals associated with AI-assisted production.
Nevertheless, AI-detection systems can produce false positives, particularly when photographs have been compressed, heavily retouched or uploaded through multiple platforms. Consequently, the results should be treated as warning indicators rather than definitive evidence of misconduct by individual hotels.
The study also did not identify specific properties or determine whether flagged changes were cosmetic, substantial or misleading.
This distinction is important because digital enhancement has been part of travel advertising for decades. The emerging concern is the speed, sophistication and accessibility of generative tools, which can make unrealistic alterations more difficult for consumers to detect.
EU Rules Increase Pressure for Transparency
The debate is gaining momentum as European regulators strengthen safeguards around misleading commercial practices and AI-generated content.
Existing European Union consumer rules prohibit marketing that deceives customers or materially influences purchasing decisions through false or misleading information. These principles can apply when hotel advertisements create an inaccurate impression of rooms, amenities or surroundings.
The Digital Services Act also places greater transparency and accountability requirements on online platforms, including travel and accommodation services operating in the European market.
Further changes are approaching under the EU Artificial Intelligence Act. Transparency obligations covering certain artificially generated or manipulated content are scheduled to apply from August 2, 2026.
The European Commission has also developed a code of practice and labelling framework intended to help organisations identify and disclose AI-generated material more clearly.
Hotels Face a Growing Reputation Risk
For hotels, artificial intelligence offers genuine advantages. It can improve image quality, support multilingual marketing, streamline content creation and reduce production costs.
However, short-term visual gains may create long-term reputational damage when guests believe a property has been inaccurately represented.
Disappointment over room size, ageing furniture, pool conditions or nearby surroundings can result in complaints, negative reviews and reduced repeat business. Booking platforms may also face declining trust when travellers cannot distinguish documentary photography from heavily manipulated advertising.
Clear disclosure could provide a workable balance. Hotels could label materially AI-generated or AI-altered images while continuing to use technology for minor technical improvements.
Travellers can also protect themselves by comparing official galleries with verified guest photographs, recent reviews, maps and videos before booking.
As AI becomes embedded across tourism marketing, authenticity will remain commercially valuable. Hotels that combine innovative visual presentation with honest representation are likely to earn stronger confidence, while platforms that improve disclosure may reduce disputes and help travellers make better-informed choices.
