I've been on both versions, and I do get motion sickness on some rides. The first time I rode orange and went with my brother. I reacted as I thought I might and felt a bit queasy during and after the ride. My brother usually has no issues with any ride and felt sick afterwards as well. The second time we had our dad with us and rode green. None of us were nauseous, and I have to say that while the orange side was definitely more intense, the green was not bad and I was pretty impressed. I thought it would be boring, but we all enjoyed it.
