I've done it, and I think it's a lot of fun. But I wouldn't wait in a long line for it! Also, my husband was very reluctant to do it, because he could see the ride from outside and to him it looked like there was a lot of spinning and upside down movements. I had to convince him that it wouldn't be that bad, because you can set the ride to your own tolerance (ie, if you don't like going upside down, you don't have to go upside down!).
Our final verdict - me, I could play with it for hours, but having to stand through the intro movie each time would very quickly get very annoying. I just want to program rides and try them out! My husband, not as bad as he feared, but not something he'll do more than once in a trip (and only if I insist).
