Think twice about the Simpson ride. We recently returned and it totally freaked my nearly 4 year old child out. She handled Spiderman easily. She adored Jimmy Neutron. She even enjoyed Terminator. But Simpsons scared her a lot. My 6 year old did fine on it, as did the boy sitting next to him who looked to be about 8. The two kids sitting in front of me buried themselves into their parents as well. They looked to be about 4 and 5 years old.
