I was totally expecting to have motion-sickness with FJ. I have a hard time on both Spiderman and Simpsons. Made a special trip to the store to stock up on the Dramamine, but never needed it. I was fine on FJ, closed my eyes a bit on Spidey, and did not ride Simpsons at all this trip. Each time I rode FJ (6X) I sat in the middle of the bench, maybe that helped.
