I bring a game boy (original) or a DS lite, but I usually just listen to my ipod. I always pick a song that is relevant to the year the attraction opened. If I were in line for Splash Mountain, I'm going to listen to some music from '89 (Paula Abdul or NKOTB anyone?). If I'm in line for Indy, I listen to some of my favorite tunes from 1995, and so on and so forth. I don't think anybody besides me will ever think that sort of thing matters but there you go. That's what I do to stay occupied; I go back in time.
