As others have said, you'll need to make a choice if you want a monorail hotel (Magic Kingdom) - Poly, Contemporary, Bay Lake, Grand Floridian - or an Epcot hotel (Boardwalk, Beach Club, Yacht Club, Swan and Dolphin). If you stay at Poly, you do have easier access to the TTC, which gets you to Epcot. But if you stay at the Epcot hotels, you're near the back of the park and the monorail lets you off at the front of the park - with a good distance in between.
