No height restrictions or fast pass. It is basically Dumbo, but high up in the sky. You ride an elevator to get up to it. The seating is such that you sit down in the rocket with your legs straight out and your child sits in front of you -- you are belted in together. Some children that age love it and others are afraid to do it b/c it goes up so high. Needless to say, it is very slow loading -- a ride best done during early entry or e-night.
