I'm so glad that someone else agrees with me that Barnstormer is sometimes a little much. My recommendation is "if in doubt-don't" There are too many fun things at WDW to waste your time feeling sick. I went on Expedition Everest once, shortly after it opened. As a lover of all things Animal Kingdom, I really wanted to like this ride. But no way! After I got off the ride, I spent about 3 hours just sitting around, trying to calm my stomach. After 3 hours, I was "up to" riding the train out to Rafiki's Planet Watch. And that night, when we went out with friends, my tummy was still slightly "off". So think of all that time wasted due to that one ride. I could have been enjoying Animal Kingdom that day, partying that night, if only I hadn't gone on EE. So I say that WDW has too many great things to do to risk feeling sick.
