True, not all 5 year olds are the same. Mine were big for their age, boys, and loved thrills like BTMRR, SM, Pirates, jungle cruise, country bears, Tom Sawyer island, haunted mansion, Buzz light year space ranger spin, mikes laugh floor, barnstormer, philharmagic, Peter Pan, it’s a small world, 7DMT. Everything else was just filler attractions but they were past being impressed with a lot of the dark rides. (Doesn’t mean they didn’t enjoy them though)
ETA- holy crap almost forgot- probably their biggest thrill at age 5 (more so than even rides) was meeting characters and getting autographs. We spent a lot of time on this
