I can understand why the TripAdvisor review are making you very apprehensive, but I wouldn't worry about it. I also made the mistake of reading Trip Adviser reviews before our first visited and It definitely had me questioning our decision. We stayed at the Dolphin, in Executive Suites, in 2011 and 2013 and couldn't have been happier with the rooms. Honestly, for our family of 5, based on the quality of the room and the price we got it for, I couldn't imagine a better value at any Disney resort. We would have booked another Executive Suite for our visit in June, but sadly because of the renovations, none were available
We ended up booking 2 rooms at the POP Century and I'm kinda going thru the second guessing right now. I've only stayed on site twice and I think our rooms spoiled us.
