I've Been to:
Boardwalk
The Yacht Club
Grand Floridian
Animal Kingdom Lodge
Despite the fact that busses are the only transportation and my room was a two day walk from the entrance DAK Lodge was by far my favorite resort... next trip im staying at Port Orleans for one night (i forget which part) and the rest of the trip were staying at Saratoga Springs, which looks nice and the pool seems cool but, i dont think either of those could ever outrank Animal Kingdom....
