One in five hotel images on booking sites now shows signs of AI manipulation, raising fresh concerns over traveller trust.

We’ve all been there.

You arrive at the hotel after a long-haul flight, bleary-eyed, jet-lagged and dreaming of that glorious infinity pool you’ve been admiring online for the past six months.

Then reality checks in.

The pool suddenly appears to have shrunk in transit, the “spacious” room would struggle to host a game of Twister, and the sparkling sea view is visible only if you lean precariously over the balcony while standing on one foot.

For years, travellers have accepted a little photographic licence from hotels. A wide-angle lens here, some flattering lighting there and perhaps a Photoshop touch-up that removes the odd stain from the carpet. That’s marketing.

But according to new research from Berlin-based ABCD Agency and German forensic AI specialist ContentGuard.me, the hospitality industry may now be entering murkier waters.

The study found that nearly one in five hotel photographs on major booking platforms shows signs of artificial intelligence used to generate or enhance images.

And suddenly, that “luxury suite with breathtaking views” may require a much closer inspection.

The researchers analysed a hefty 25,550 hotel images from 700 properties across seven destinations in May this year. Their forensic software searched for tell-tale signs of AI involvement, including suspicious metadata, irregular pixel structures, and visual inconsistencies often left behind by generative AI tools.

The result?

A total of 4,778 photographs, or 19 per cent of all images examined, raised at least one AI-related red flag.

That’s not exactly small change.

Crete Tops the “Hmm, Really?” List

Among the classic Mediterranean holiday favourites, Crete emerged as the destination with the highest proportion of potentially manipulated imagery.

Almost one in four hotel photos analysed on the Greek island, 960 images from a sample of 4,139, displayed signs suggesting AI involvement.

Put simply, travellers browsing hotels in Crete may want to pack an extra serving of healthy scepticism alongside the sunscreen.

Mallorca performed comparatively well, with only 9% of photographs flagged.

Sicily registered 11 per cent, while Turkey’s perennial favourite Alanya came in at 13 per cent.

Then came the surprise packet.

German city destinations delivered the study’s highest figures by some margin. Hamburg topped the table with a staggering 36 per cent of images flagged, while Berlin recorded 27 per cent.

Researchers believe one reason may be the widespread use of destination imagery featuring landmarks and city scenes rather than photographs of the hotels themselves.

Still, whether it’s a skyline, spa, suite or swimming pool, the bigger issue remains exactly the same.

Travellers are making increasingly expensive decisions based on what they see on a screen.

Holidays Cost Too Much for Smoke and Mirrors

Booking a holiday today often involves spending several thousand dollars after little more than an evening scrolling through photos on a mobile phone.

Those images matter.

In fact, travel marketers have known for decades that photographs frequently make or break a booking.

The concern is that AI can now alter reality in ways traditional editing never could.

Rooms can appear substantially larger. Furniture can magically look newer. Gardens can become lusher. Pools can expand. Beaches can become bluer than a Queensland tourism brochure in full flight.

And let’s not even start on sunsets.

We’ve all seen sunsets online that appear so spectacular you’d swear Mother Nature had engaged a Hollywood lighting director.

The problem comes when guests arrive expecting paradise and discover something considerably more… earthly.

Disappointed customers complain. Review scores slide. Trust evaporates.

In hospitality, trust is everything.

Once travellers begin questioning whether photographs accurately represent a property, everybody loses hotels, booking platforms and consumers alike.

Jens Kramosch, deepfake expert and founder of ContentGuard.me, says the industry is approaching a dangerous tipping point.

“Hotel photos have always been retouched to some degree. But AI takes this to a completely different level. When images are no longer just polished but fundamentally altered, it risks crossing the line from marketing into deception. Travellers need to look more closely and platforms need to start labeling AI-edited content transparently.”

Robin Wilfert, founder of ABCD Agency, agrees.

“When you book a trip, you’re buying a promise. The photos that travellers use to choose a hotel are the most important part of that promise. AI must not be allowed to create a gap between what’s shown and what’s real.”

The Industry’s Next Big Debate?

Artificial intelligence is not going away.

Nor should it.

Used responsibly, AI offers enormous benefits for travel companies, from improving image quality to streamlining marketing workflows and reducing production costs.

But somewhere between removing a cloudy sky and digitally constructing an entirely different hotel experience lies a line the industry ignores at its peril.

Expect calls for mandatory AI labelling on booking platforms to grow louder.

Because in travel, selling dreams has always been part of the business.

Selling fantasies masquerading as facts is something else entirely.

And no traveller enjoys discovering that the best thing about their hotel stayed behind on the website.

Methodology

In May 2026, researchers analysed 25,550 hotel photographs from 700 randomly selected hotels across seven destinations. ContentGuard.me’s forensic AI technology examined metadata and visual anomalies, including inconsistencies and irregular pixel patterns. Images were flagged where at least one AI-related signal was detected. The study did not differentiate between fully AI-generated and AI-enhanced photographs.
