I've been on a whopping TWO!
1. Refurbished (as well as Rockin' and GG) Space Mountain @ DLR
2. RotM @ USH
Ever since my first ride on it, I have LOVED Space Mountain. I was fascinated by the com chat in the queue, the visual effects, and - duh! - the ride. The overlays were also neat, so there ya go.
