Lights! Motors! Action! show at MGM should be good. I was sitting next to a couple of 20-something men when we saw it, and they couldn't keep quiet about all the great techno/muscle stuff. He also might like the Backlot Tour at MGM; I liked the way they redid the first part to link it to the making of Pearl Harbor. And then there's Rockin' Roller Coaster there, too.
