Tomorrowland offers Buzz Lightyear Astro Blasters, the Rocket Jets (like Dumbo, the rockets fly in a circle), and the very impressive Finding Nemo Submarine Voyage. Space Mountain (a roller coaster that ricochets through the dark) is a thrill for older kids and parents alike. StarTours, one of the best attractions in the park, also tends to frighten the younger set, so watch out.
