I have not had a problem with a crowded bus at BWV yet. Did have one time at OKW. The driver called dispatch to send another bus. You could also go to Epcot and use the monorail but that is a little complicated. I think you have to switch monorail lines. I also have "walked" to MGM and taken the bus from there to various places like other resorts and parks. The busses are generally empty after dropping off at the park.
