Not worth it if you are going to close your eyes the whole time.
I don't think I'd ride it again just because it's a good chunk of change to ride it, but it was worth it to at least say I rode it. It was fun, and we went kinda late at night (10? 11? I forget...) so there was not as many people. They also have a couple going at the same time so we did not have to wait very long.
So, if you're going to ride it, I suggest you go at night and you wear a sweater.
Oh and bring some change to store your stuff in a locker because they won't let you take anything with you.
