Pros: Great Transportation , Best Resort Pool (the only resort pool licensed as a water park - 3 acres), the best access to some of the best restaurants (such as the ones in Epcot, Boardwalk), great ice cream floats at Beaches & Cream, Rooms have a day bed and sleep five, quick access to Epcot (back entrance), Boat ride to MGM.
Cons: None that I can think of except that the rooms are small.
