I am a super wimp and I like Gringotts. I have ridden it 7 times in the last 2 days. I do not row 6 though, it makes the drop seem scarier. Ask for the first car - row 1, 2, or 3.
I am getting prone to motion sickness in my old age and FJ is hard for me. I can do it once for my DD, but i feel nauseous for awhile afterward. It’s the screen that gets me, not as much the motion. I can make it through if I close my eyes. It’s is a thrilling ride, and I enjoy it as much as one can while getting uncomfortable nauseous. But lots of people get off feeling queasy. We are here now and I let the attendant help me step off the moving platform today. It was a low moment, but I have a bum knee and the nausea was making me a teensy bit woozy.
My DD and I are big Potter fans (to the extent that if there is more to Universal, I don’t really know what it is, lol). I am glad I rode FJ, but I could easily never do it again. I love Gringotts though, the ride is very smooth and the drop isn’t very scary. I don’t do real rollercoasters.
If you don’t do the rides, do go through the line anyway, particularly FJ, the castle is really cool inside.
