I LOVED THIS THING!
I dislike flying in a plane but I'll hang from a cable any day. (I guess in my crazy "I don't want to die" cerebral classification system, I regard this as "amusement ride-ish" and considering strapping into this thing didn't scare the heck out of me!) That stated, my best advice is still "Don't look down!" At least not while you are up on the platform. (5 stories up) I did, & got a bit of vertigo but it stopped as soon as I was screaming (literally) along!
Other reviewers have written awesome reviews about the process etc. -here's a couple things I'll echo/add:
* they told us 15 min wait, was more like 45
* you can stop the spinning by holding out your hand if you dare loosen your grip! (my husband did this and flew a straight ride, I was doing 360s!)
* there's a wicked jolt at the end just before you reach the other platform - "WHOA!!" - it scared all four of us - don't worry you aren't gonna die, it's just slowing you down.
I think this is a great place for a first time zipline experience (inexpensive, short distance traveled, fun crowd)
Time & money well spent!
