Things that might scare little ones at Disney World -- I would add that the scene from Alien in The Great Movie Ride at Hollywood Studios could be terrifying. And my 9-year-old nephew did not like all the loud noises at the HS stunt shows. A few of these ... while not terrifying enough to make me skip them ... still create a knot in my stomach (and I'm a grown-up)!
Tips from the Disney Divas & Devos: Disneyland and Walt Disney World Photo Tips with Toddlers ... Two other tips I'd like to add: Please have your cameras, autograph books and pens (and backup) ready for when it is your turn. (And your child should be out of the stroller when you're next in line). And along the same line ... please be considerate of those waiting in line behind you by not "hogging" the character for an excessive amount of time.
