I just did it with my niece & it was $174 for the tandem. She loved it & wants to go again. I loved it but don't need to go again. The thing that I didn't think of, is when they say 450', that is rope length, not height. I don't think we were all that much higher than the contemporary, maybe 50 feet higher. For $12.95 they will shoot a role (12 exps) of 35mm film for you. I don't think they will take your pictures with your camera anymore, and you're not allowed to bring it up with you.
I recommend it at least once.
