I will ride anything at least once. There is absolutely no ride at Disney or anwhere else for that matter in which I won't ride multiple times. My DH, on the other hand, now that is a different story. We will not ride any ride that spins.
I love the tea cups, so on our last trip I broke down and rode it by myself, but it's not as fun with only one person spinning. And Mission Space...thank goodness they had the singles line for that ride. I rode it alone, because my DH was leary of the ride, because it spins. So, I rode it and advised him against riding it...I didn't want him to risk getting sick.
I just love thrill rides!!!
