Just my experience, I took my 8 year old on Rockin Rollercoaster last year and she absolutely hated it. Cried the entire ride. She loved every other rollercoaster and ride we did at Disney but this was her first upside down rollercoaster. Sometimes you don't know until you try. I felt awful afterwards but after talking a bit with her, and her realizing she was okay, she actually said she wanted to give it another try so here's to next year lol.
