I did MS Orange shortly after it opened. There was no Green then. It killed an entire day for me. I cannot do spinning. Absolutely not. And, btw, I was totally fine during the ride. It was after that was the killer. I was dizzy for several hours. Had to go back to the resort. I was staying at AKL at the time, savannah view, so it wasn't like it was a punishment!
I'm totally fine on both Soarin' and FoP. My DH, however, can't take FoP. I believe his difficulty on the ride has to do with his progressive lenses, although he's not sure. After FoP, he had a bit of trouble on Soarin', which he'd never had a difficult time on before.
