It's always so hard, isn't it? My son loved it when he was 5. I suggest maybe looking at it with your kids on youtube prior to riding it. My boyfriend's 10 year old cried and freaked out on Forbidden Journey this year, which shocked me since he LOVES Harry Potter -- but he also had never really been to an amusement park. Whereas, my son, now age 8, has been wanting to ride the Hulk since age 3. I showed him FJ on youtube and he said, "I can handle it. GET ME ON IT!" So, it just depends on the kid.
