I love tripadvisor because anything said there is probably wrong. I was looking for Thai food and there was this lovely Thai restaurant close by. It was dark, hot, dingy, dank, and they only took cash because the credit card machine was down. It was rave review and sounded so good.
tripadvisor is open to anyone who wants to join and review. I have seen some reviews of places that I think are great that are lies. If the Dolphin or any WDW site was dangerous, moldy, or otherwise then one person would have reported in on a board, chat room, forum or other place then word would have spread. People would have agreed and added more info or debunked the story as you seen here.
I may be going to San Antonio in 10 days and their suggestions were so wrong that I only used it for the amusement parks and that was common knowledge. I see it as an affiliate site where people give free reviews and the site makes money from affiliates such as google.
