I have claustrophobia. I will never ride Mission Space again. I don't ride ToT or RnRC, but that is mainly because I'm also afraid of dropping and the speed of RnRC. I try to avoid choke points (places like the pathway from small world to Haunted Mansion). Honestly, what has made me panic the most at WDW was being on certain rides when they break down - anything that straps me in or is in an enclosed space. For instance, we were on Millennium Falcon when it stopped and were trapped in our seat belts in the capsule for about 15-20 minutes. I started banging on the door, hoping they would let us out. There is always a chance a ride might break down, so I really have to keep that in mind when choosing rides to go on.
