There is no shuttle that I know of. They are fairly close together so you could walk to them. I don't know if I would walk from movies to sports as they are the furthest away from each other. It would be easy to walk from Music to either Sports or Movies as it is in the middle of the two. Sometimes all three resorts share park buses so I suppose you could ask a bus driver if they are stopping at the other all stars. If they are sharing buses the stops are sports, music, then movies.
