"Robo: In JUNE, the Dis/MGM Studio will still be open (or just "closed") after IllumiNations. (Check the closing times before you do this.) Take the Friendship from the Epcot International Gateway to the Dis/MGM Studio. (You'll be back in WS already and there shouldn't be "too many" folks going that way.) The boat-ride takes 30 minutes. From the dock, you'll exit the boat right near the Studio's bus lot. Take the bus from the Studio directly to Ft. Wilderness' Pioneer Hall. Change to your internal FtW bus."
This is not a bad idea either. MGM closes at 10:00 pm. Is the bus ride to MGM longer than the bus ride to the Beach Club? However, at the Beach Club, we wouldn't be able to get directly on the bus to FW, would we?
