Plumb

Find reviews of a hotel

Who reviews a hotel, and can you trust them?

Plumb does not review a hotel itself. We tell you which sites do, and grade each on the one thing that decides whether to believe it: how independent and evidence-based the ranking is.

Which? High Scoring Confidence Paywalled Hands-on tester
Grades: its lab-tested 'Best Buy' product verdicts
A rare reviewer that buys and lab-tests products itself, takes no ads, and by its own disclosure keeps paid logo-licensing walled off from its ratings.

2 B+
Michelin Guide High Scoring Confidence Hands-on tester
Grades: its anonymous-inspector restaurant stars
The gold standard for hands-on, anonymous restaurant review, but its independence carries an asterisk now that tourism boards pay six figures to bring the Guide to town.
35325
3 B+
Eater Medium Scoring Confidence Editorial reviews
Grades: its curated restaurant guides and criticism
A staff-curated food-media guide where restaurants can't buy onto the list, but the "essential" picks rest on editors' judgment, not a published, reproducible scoring method.

4 B
The Infatuation High Scoring Confidence Editorial reviews
Grades: its staff restaurant reviews and city guides
Genuinely independent restaurant reviews, owned by the bank whose card perks they feed.

5 B-
OpenTable High Scoring Confidence Marketplace
Grades: its diner-verified ratings and 'Diners' Choice'
A reservation platform whose star ratings come only from verified diners — but the restaurants it lists are also its paying customers, and some pay to rank higher in search.

TripAdvisor High Scoring Confidence Crowd reviews
Grades: its open user reviews and 'Popularity Ranking'
Anyone can post without visiting; ~9% of 2024 reviews were caught fake, and hotels buy the slots above.
23432
7 C+
Booking.com High Scoring Confidence Marketplace
Grades: its guest review scores and relevance ranking
Verified guests give it real review data, but the properties it ranks also pay commission and can bid for top placement, so the ordering you see is partly an ad auction.

8 C+
Cruise Critic Medium Scoring Confidence Crowd reviews
Grades: its passenger-review ratings and cruise awards
Real cruisers and sea-tested editors drive the ratings, but Cruise Critic earns booking-referral commissions and doesn't publish the thresholds or verification rules behind its awards.

9 C+
J.D. Power High Scoring Confidence Ratings & rankings
Grades: its customer-satisfaction surveys and 'highest-ranked' awards
An award you mostly hear about because the winner paid to license it.
23323
10 C-
Kayak High Scoring Confidence Marketplace
Grades: its flight, hotel, and car comparison results
A slick travel meta-search that compares hundreds of sites, but by its own disclosure its "Recommended" ranking factors in revenue potential and may down-rank cheaper offers that hurt monetization.

Skytrax High Scoring Confidence Ratings & rankings
Grades: its airline and airport star ratings and awards
The self-styled "Oscars of aviation" runs free passenger-voted awards alongside a paid audit/certification arm, and critics say earning money from the airlines it rates clouds its independence.
