At Tripadvisor.com, hotels are reviewed and selected for the TripAdvisor Travelers’ Choice based on the unbiased reviews of millions of travelers at the site. One of the most entertaining entries i've seen at TripAdvisor.com can be found here.
This review awards the dirtiest hotels, unlike the usual most romantic award, or best luxury hotel, that sort of thing. No, this post is entitled Great Hotels for People You Hate, and is targeted at pointing you to the worst possible places to stay. It is a fun read-through, and offers good, er... recommendations? Well, recommendations of places to avoid, at least!
Take a look at the site. It is amusing, and might save you some headaches before your next trip.
