Yeah BVS for sure! Especially as its a nice homage to him and parrallels MS. Also, Indy and Fantasmic. Splash Mountain would also be nice.
But if someone could show Walt other Disney theme parks but from his concept, hands down Tokyo Disneysea! It is probably the most immersive well detailed park done anyway. It takes the DL model and raises it another level. People who say Disney doesnt know how to do Disney anymore should look at that park when the checkbook can go as far as their imaginations.
