I think it depends on what causes your motion sickness. If it's shaking and jarring movements that get you, you'll be fine because Soarin' is incredibly smooth (pregnant women can ride this). If you're motion sick from any kind of motion, then you might have a problem. The way I describe the ride to those who've never ridden it is "an incredibly smooth, multi-sensory motion simulator." CA is a beautiful state. Everytime I ride it I think: Oh, yeah, that's why I live here.
