I'm a TA user, poster, trip advisor. I think there is some very useful information to be gained from the site both about hotels and travel destinations.
That being said, I think it is also prudent to keep in mind that most people will go out of their way to complain about something that is wrong but will rarely go out of their way to give praise for excellence. This site is devoted to people who do nothing but go to WDW. Those sites are devoted to.....everyone! I love WDW and may get flamed for this but I know going in that I can get a MUCH nicer, larger room, with great ammenities in many other locations (including "near" WDW) for the same or better price than I am paying to be on site. But that is what I am paying for....being on site, the experience, my magical express transportation, my "resort fee" for transporatation, etc etc etc. I do believe that by and large WDW rooms are way too small especially in the Deluxe catergories, but again, I know going in what I'm paying for!
Bottom line, take everything you read anywhere with a grain of salt and look at averages not individuals. If more people would adopt our 2 for 1 rule (for every one complaint you feel compelled to make, find two things or people to praise and that means talking to the manager!) and I think we would see a definite shift in people's perspectives about places.
