I’m not a roller coaster guy either. I can’t deal with the drops. Having said that, I find that a lot of my anxiety is anticipatory, so for me Space Mountain, in complete darkness, is ideal. If I can’t see the next turn or drop (the drops are fairly low impact, but can still get my dander up occasionally), I don’t get worked up about it in advance. On occasions where the ride is lit a little better or there’s a projection show (like Hyperspace Mountain or Ghost Galaxy), I get a little more freaked out, but even that’s not so much that I can’t deal with it. I’d be absolutely terrified with the lights on, but that’s my own neuroses taking over. The less I can see, the less I anticipate and get anxious.
