After reading this thread, I can't determine if posters are bashing trip advisor relating to Disney hotels only or trip advisor as a whole. I post a lot on trip advisor and I rely heavily on it when I travel. I find it an extremely helpful tool when traveling. Can't imagine staying somewhere that I have not reseached on trip advisor first. Not only hotels are reviewed but activities, tours, etc.
Disney hotels are different because Disney classifies their hotels within the scope of WDW as a whole. Some posters on trip advisor apparently don't realize this but their opinions are important. Not everyone travelling to Disney realizes that a Disney Deluxe may not be considered a deluxe resort outside of Disney. So reading some negative reviews on trip advisor may enlighten travellers that Disney hotels/resorts are not the same as others outside Disney.
I've been on the Dis for years and have a pretty good understanding of Disney resorts. But, I understand that although people might do research before a trip, not everyone can spend a ton of time researching, thus, some negative reveiws from non-dissers may be beneficial to others.
I think most people can pick out silly negatives regarding any hotel and try and take in the whole picture. I've found the Dis a valuable tool for
Disney vacations and trip advisor a valuable tool for all travels.
