About to go to Disney World for the first time, but I've been to Disneyland many times. I get motion sickness and I'm trying to figure out if I can handle certain rides. I'm wondering if you can tell me how Expedition Everest compares to other rides I've ridden before like Big Thunder Mountain or Space Mountain. I've never gotten sick on Big Thunder Mountain, but Space Mountain can make me a bit queasy sometimes. Can you tell me how Expedition Everest compares to these to and how likely you think it is to make me sick. Thanks!
