Do you stay in hotels a lot? TripAdvisor has compiled a list of the USA's dirtiest hotels? Stay away from these. TripAdvisor
is a wonderful site because you can read reviews written by actual travelers (I am a member and write reviews on my own hotel stays) and see photos taken by travelers which are usually much more realistic than the polished photos available on hotel websites. Click on the review from "Hotel Carter" in NYC and click on a specific review. Once you do you will see a link at the top for "traveler photos." Click on that and you will be totally grossed out.
