They can be read in the review section, but experts warn that the vast majority are unlikely to click through to find them.\n\nMartyn Slack, who runs family travel YouTube channel Three Tickets Anywhere, researches hotels hands-on for a living and hits the ‘same misleading AI overviews’ that travellers do.\n\nThe problem, he says, is that most people ‘don’t take that extra step’ to check reviews direct on the hotel’s site.\n\nMartyn adds: ‘For budget-conscious parents especially, an inaccurate overview isn’t just annoying, it can mean an unrefundable non-cancellable booking that turns out wrong for their kid.’\n\nExperts tell Metro that AI overviews prioritise ‘fluency over accuracy’ (Picture: Getty Images)\n\nAnother of Tripadvisor’s AI tools, an interactive trip planning bot called Ollie, also failed to warn holidaymakers about poor hygiene.\n\nWhen asked directly about the risk of contracting food poisoning at the Riu Palace, Ollie said food poisoning was ‘quite unlikely’, and that the resort had a ‘strong reputation for high hygiene standards’.\n\nWhen the consumer champion asked Tripadvisor about its AI summaries, it said it prioritises ‘transparency and impartiality’.\n\nIt added that its summaries ‘surface a range of both positive and negative community feedback associated with listings’.\n\nTripadvisor also told Which? that AI chat assistant tool Ollie ‘draws from a selection of reviews based on detail and recency, and matches by language and context’, but it added that it is a ‘product in development’, and that it is now actively looking into several examples the consumer champion provided where reviews did not match.\n\nThe Riu Palace wasn’t the only hotel that Which? found serious reports of food poisoning missing from its Tripadvisor AI summary.\n\nSeveral guests who stayed at Garza Blanca resort in Cancun in the past 12 months also left reviews saying they fell ill, including a wedding party.\n\nYet Tripadvisor’s AI overview is once again glowing, describing ‘immaculate cleanliness’, adding that its dining options ‘earn [it] positive feedback’.\n\nAnother example was the Occidental Caribe in the Dominican Republic. Recent reviewers called it a ‘disaster and disturbing’ as recently as March 2026. Another called it the ‘worst place imaginable’.\n\nOne guest said her room smelled of sewage and that half of the 68-person wedding party she’d travelled with fell ill.\n\nSomeone who visited in January reported that the whole hotel smelled of mould.\n\nSeveral mentioned the lack of access to running water – one guest resorted to showering with bottled water.\n\nIn contrast, the AI review summary talks about the hotel’s ‘abundant’ amenities, with only a vague nod to ‘inconsistent’ cleanliness and ‘maintenance issues’.\n\nThere are other dangers Tripadvisor’s AI summaries don’t share.\n\nComment nowHave you had a negative experience with AI hotel overviews? Comment Now\n\nAt Kaia Coracesium on the Antalya coast in Turkey, several reviewers who visited last summer wrote they felt unsafe due to repeated sexual harassment from male hotel staff, including inappropriate jokes and gestures, and repeated requests to connect on social media.\n\nTwo different guests reported that a male member of staff followed their daughters to request their social media details.\n\nIn one of these cases, the reviewer says a restaurant worker followed her up the stairs to her room.\n\nThe Tripadvisor AI review summarises the service as ‘friendly’. The closest it comes to referring to these serious allegations is: ‘Lapses [in service] noted by a few’.\n\nThis suggests that the company’s AI systems are capable of identifying and referencing these allegations, recognising that concerns raised by even a minority of reviewers may warrant inclusion in its summaries.\n\nHowever, questions remain as to why such references do not appear consistently and, when they do, why the language used appears to minimise their significance.\n\nTripadvisor said its summaries ‘use large language models and natural language processing to read recent reviews, identify the most common themes and then turn those themes into short, plain-English overviews’.\n\nIt said its goal was to ‘make content from Tripadvisor’s reviews and opinions as easy as possible to digest, but also to capture and highlight the broad spectrum of positive and negative opinion without favouring one sentiment or the other’.\n\nTripadvisor told Which? that summaries are updated on a monthly basis ‘and are rooted in the previous 12 months of reviews at the time of each update’.\n\nIt said reviews are treated equally regardless of rating, highlighting what reviewers mention most often.\n\nFor comparison, Which? looked at rival platform’s approach to AI summaries for hotels.\n\nGoogle manages context in their AI summaries far better.\n\nGoogle’s overview for the Riu Palace warned of ‘potential for illness’ and flagged ‘outbreaks of illness’ and ‘concerns over birds in the buffet areas’.\n\nThe consumer champion also compared Google’s AI overview to Tripadvisor for Britannia hotels, the worst-rated chain in Which?’s hotel survey for more than 10 years.\n\nFor the Britannia International hotel in London, Google accurately shared that the hotel was ‘frequently rated as one of the worst hotel chains in the UK’ and further highlighted guest reviews of ‘filthy’ conditions and ‘horrendous’ service.\n\nTripadvisor’s own summary of the same hotel said guests ‘often praise the clean rooms’ and described the atmosphere as ‘charming’.\n\n## What the experts say\n\nOli Huggins, CEO of ExpertEdge and VP of Partnerships at Packt Publishing, is ‘an AI advocate and a generative AI sceptic’.\n\nWhat he distrusts, he says, is generative AI that is asked to produce fluent prose with nothing underneath it.\n\nAnd because a hotel overview is exactly that, it fails ‘in three predictable ways’.\n\n‘The first is that these systems are trained to be agreeable, so they lean positive by default,’ Oli tells **Metro**.\n\n‘Ask for a summary of almost any hotel and you get a warm one, because upbeat, accommodating prose is what the model has been rewarded for producing, not because the place earned it.\n\n‘The second is cliché. A model reaching for the most probable next word lands on “charming,” “convenient location” and “perfect for families” precisely because those are the most worn phrases available, which means the overview reads as reassuringly familiar while telling you almost nothing specific.\n\n‘The third, and the dangerous one, is hallucination.\n\n‘When the model does not know something it does not stop, it fills the gap with a plausible invention delivered in the same confident tone as everything else, so a pool drained two years ago is described as a highlight, and nothing in the prose signals which parts are real.’\n\nPut those together and Oli says you get fluency standing in for accuracy.\n\nNupur Khurana, a former AI consultant who works with QXP India Travel, a boutique luxury destination management company, agrees.\n\n‘The danger isn’t that [AI summaries] are wrong, outright, it’s that they present with total confidence regardless of accuracy,’ she tells **Metro**.\n\n‘A summary can carry an outdated fact, a review taken out of context, or a detail invented altogether, and it reads with exactly the same authority as everything else on the page. Most travellers have no way of knowing which parts to question, so they don’t question any of it.’\n\nOthers say Tripadvisor’s response is missing the point.\n\nRory Boland, Editor of Which? Travel said: ‘Tripadvisor may insist users can still fact-check its summaries against real reviews, but this ignores the fact that it made the decision to push these summaries to the very top of the page.\n\n‘This failure to surface critical safety information is unacceptable and potentially life-threatening.\n\n‘The platform has a responsibility to revisit the accuracy of its AI summaries and AI chatbot. In the meantime, users should scroll past these summaries and look at guest reviews, particularly one-star ratings, and at reviews on other sites, to make sure their next stay is a safe one.’\n\nComment now Comments \nAdd Metro as a Preferred Source on Google\nAdd as preferred source\n",
