I know that Swan/Dolphin, Boardwalk, and Yacht & Beach Club are all there together. You can walk to Epcot from these places - you enter at the International Gateway between England and France. From the Fort, we took a bus to Epcot and walked around a while- then a boat to Hollywood Studios (from Epcot) for the kids to meet some friends, then to the Boardwalk for some exploring, then the boat back to Epcot, and a bus to the Fort. It makes for a nice break in the middle of the day.
