This is a outright scam site. They manipulate ratings in favour of places that have been rated poorly; negative reviews can and will disappear – it has happened to mine.
I would also point out that more than a few people have had problems with this business:
They also engage in keyword stuffing in Google so that if I type "<almost anything> plus a place" I get a first page hit for tripadvisor that does not include any mention of my search subject whatsoever. I routinely must filter out Tripadvisor in most of my searches as a result. They even pop up during a search for a German conspiracy far-right group.
This is black hat SEO and for that reason and the various pop-unders on their site, I must label them as untrustworthy.
Super handy when planning our vacation and very useful during the staying (find locals restaurants).
At the last years, there is a lot of fraud and the score is a little bit bias, so check the reviews before taking the decision only by the rating.
From one hand - Trip Advisor is a very convient website (and app), I totaly trust them. The site is well known and 100% safe.
However - I don't 100% trust the recommendation given there. I don't know how do they decide to give resturant 5 stars? Sometimes there is no corellation between the quality to their ranking.
This site has a very blatant inherent conflict of interest: they edit and censor reviews while accepting advertisements from the very companies that are being reviewed. There are two motels locally who received unfavourable local newspaper coverage for renting some of their rooms monthly under little better than flophouse conditions: one was an independent (Kozy Inn), the other was a member of a national franchise brand. Predictably, the low-end independent motel got trashed in reviews and was listed correctly as one of the worst of the various local alternatives. The franchise motel? The underlying property was just as bad, but their review suddenly came complete with a response from the proprietor and a rating conveniently lower-middle instead of at the bottom where they belonged. Why? One innkeeper had the backing of a chain and a bit better support in being able to work the system.
TripAdvisor is bad for censoring reviews. If criminal activity is taking place at a hotel/motel, expect that information to be excised or deleted. If the property's website is misleading, expect any review to be edited - not to warn the public, but to remove the direct link to the property from the review body text. Why? TripAdvisor wants to position themselves as middlemen and drive traffic to their own booking engine - not directly to the motel the way a listing in a reputable travel guide (like Wikivoyage) would link directly.
It's unfortunate that censorship and self-serving activity taints what otherwise would be a useful and valuable tool. There is a lot of good user-supplied info - usually travellers will spot a once-reputable hotel going downhill long before the locals do, as the locals are at home comfortably asleep in their own beds.
If anything, though, the censorship is worse than the already-severe manipulation of reviews on sites like Yelp as a review (instead of being randomly taken down without plausible explanation) doesn't even appear until it gets past staff at TripAdvisor.
Pity. I can't say "don't look at the reviews" as sometimes they're useful, but a company purporting to review hotels should not be in bed with hôteliers the way this company seems to be - selling ads, inviting properties to display "approved by TripAdvisor" stickers or flags, basically engaging in promotion for vendors.
It's much safer to check sources who send out their own reviewers - either automobile associations or national standards groups like Canada Select. Any of the current crop of websites is about as reliable as an "escort review board" sponsored by ads by the "ladies of the night" being reviewed - which is also easy to find and limited in its value beyond flagging obvious fraud or crime.
Users' reviews on restaurants, hotels, airports, airlines and other P.O.I.s., and ratings, as well. However, be careful: all reviews are moderated and - according to my own experience - negative reviews are usually blocked by the moderators. Alas, the page itself is quite safe.
