The Epcot resort area is around a lake (I believe it's Crescent Lake). On one side you have the Yacht Club and next door is the Beach Club. The BC is closest to the International Gateway of Epcot, about a five minute walk.
On the other side of the Yacht Club is the Dolphin and right next to it is the Swan. The Boardwalk is on the other side of the lake across from the Yacht Club and next door to the Swan. It's a great area to walk around and shop and eat. Check out the menus for all these resorts on allearsnet.com.
The Friendship boats service the Epcot resort area. They run continuous service from the Epcot IG to the Disney Studios stopping along the way at the Yacht/Beach clubs, Boardwalk, and Swan/Dolphin. You can also walk to the Disney Studios from this area in about 15 minutes. The Boardwalk is closest to the Studios and the walking path is along the side of the Boardwalk.
