It does depend on the kids. They are less likely to be afraid of the villains if they know them. My DD could name all the villains and therefor knew there was nothing to be afraid of. She was 3 when we first saw it. She never liked loud music, noises, etc. but I let her wear earplugs through most Disney attractions. As for the wait, well yes it is long. We like the primetime cafe for dinner so we never do the dining package. I think overall it's worth it. In my family, we refer to a "DISNEY MOMENT" as the moment when, after you've done the planning and arrangements and maybe you've done some stuff there and it's all flying by like any other trip. Then all of a sudden you realize you're at DISNEY WORLD!!! And you just sit back and enjoy. well, fantasmic is alway smy Disney Moment. Even I, at 29, get a rush of excitement when the lights come up and Mickey's is on the top of that mountain!!! Be prepared....prepared to enjoy!!
