We had Tony for our experience, and it was a great time. I think he's got a really outgoing personality, and seemed to keep everyone pretty calm for what is a really intense experience. It was NOT exactly what I'd expected, I felt like a lot of what we did was to eat up time, and I was actually sore for a day or so (mostly pecs). Also, if it's a hot day outside, you're going to have 120mph hot air blown at you. It's going by so fast you won't break a sweat, but this is just a list of the things I was not expecting out of the experience.
They don't seem to take reservations, but we showed up at 1030am or so on a busy saturday in Vegas, and we were in pretty quickly. Set aside an hour for the experience plus however long the wait is for the next opening.
