Great thread! I've been reminded of several attractions and snacks I wouldn't have remembered otherwise.
My list includes People Mover, Tom Sawyer Island, Flights of Wonder, Hall of Presidents, the China film in Epcot, Sum of All Thrills, and Captain EO. Rectifying most of these on our upcoming trip except Captain EO.
Snack/meal list includes Mickey Bars, 1900 Park Fare, and CRT. Will definitely try to grab a Mickey bar, but the fact that we're trying out several new restaurants already (including Sanaa, H&V, CP breakfast, SRT, and B&C) means that the rest will have to wait until next time!
Star Wars weekends (and actually, come to think of it, all of the hard ticket events) are also on the to-do list. Geez, we haven't even left yet and now I want to plan the next vacation!
