DD now 12, who is generally not freaked out over anything just about lost her mind when she went on Jaws for the first time at 8. Expecting that it would not scare her, but rather thrill her, I didnt tell her about the big shark jumping out at her - she was petrified, so much so I thought she was kidding. This time, even though she knew what was coming, was reluctant to get on. She did though, and was still freaked out. You just never know.
This is the child is sobbed enough to break your heart when she was younger because of height restrictions. No other ride at WDW or US, or anywhere for that matter have ever even caused her to blink an eye.
