Indoor skydiving at IFly is a super interesting and awesome thing to do. You have to make a reservation before hand, and 2 flights cost $90. You then sit with your group and instructor and the instructor tells you hand signals he'll be giving you in the tunnel. My instructor Dusty was very nice and made the situation before a little less nervous for me. Once you have trained, you get onto a inclosed bench near the tunnel, and the people sitting before you fly. Once it's your turn, your instructor takes you inside the tunnel and you fly. You can do a high fly, which means you can go higher in the tunnel, for a higher price. You have one minute in the tunnel, and then your instructor takes you out. That is one flight, then you go again. You can purchase four flights for a higher price. Overall, the experience is incredible, and I'd definitely recommend it and do it again.
