The Beach Club and Boardwalk, along with the Yacht Club, Swan and Dolphin are all located in the Epcot resort area. The closest to Epcot is the Beach Club with the Boardwalk (maybe the Swan) being the closest to the Disney Studios. However, they are all within a ten minute walk of each other at most. The Friendship boats service this area travelling between the Epcot International Gateway and the Disney Studios throughout the day. Along the way the boats stop at the Beach/Yacht clubs, Boardwalk, and Swan/Dolphin.
From the BC you would want to take the five minute walk to Epcot. To take the boat you would have to walk away from Epcot towards the Yacht Club. The walk from the Boardwalk to Epcot is maybe ten minutes tops. From the BC the Studios is maybe 15 minutes walking and ten minutes from the Boardwalk. You would probably want to take the boat to the Studios. The bus service from there is ususally shared depending on the season. In June our bus from the Boardwalk shared with the Swan and Dolphin. Back then the Beach and Yacht clubs had their own buses. In the slower seasons all five resorts share the buses. You would only need buses to go to the Magic Kingdom, Animal Kingdon, water parks, and Downtown Disney. Since we spend so much time at the Studios and Epcot we love staying in this area.
