Rode twice last week. No matter how much you hear about it before you go, the experience will not be what you imagined. It is indescribable! This is one of the most thrilling rides I have ever been on.
It is very gentle and even people subject to motion sickness will probably not have a problem. For those afraid of heights: I am mildly afraid of heights - for example, I will not go near a railing of the hotel above about the second floor. But after the initial shock of feeling like you are flying around, there is no problem.
I am glad there was some discussion about being distracted by the feet. I was in row 2 the first time. If you put yourself in the frame of mind that you are flying around with 90 other people in a hugh hang-glider, the feet are not distracting. It is only distracting if you try to imagine that you are by yourself.
When I flew in row 1, I was occasionally distracted by seeing the top of the screen, which you cannot see in the second and third row. Also, I felt like I was bending my neck to look down a lot, whereas in the second row I was looking more straight ahead.
So each row is a little different experience. I'd like to ride in the third row next to see what that's like. I've heard people say it feels like you are closer to objects you fly over.
