I bought this as a gift for my dads birthday and it took us a few tries before we could actually set a date that worked. The front desk was always accommodating when I called to change the date/time yet again. Today we finally made it there. Check in was easy, with most of the details being punched into a tv touch screen by us. Then we had to sign our waivers, show our ID and be weighed before heading up.
We had to wait for about half an hour before we began our training - this was a bit annoying. It was fun watching the others ahead of us in the flying chamber, but by the thirty minute mark we were bored and just wanted to get on with it!
We went into the room where we watched a brief video and were educated on proper positioning and what the various hand signals went. Following that we put our stuff in lockers, suited up and went into the chamber. There is a bench inside and we went one by one (obv), but a guy getting 1-1 lessons went in between every three members of our group. That was a bit confusing.
The instructor Julien was fantastic. He was very patient, calm and just all around great in not only preparing us but also taking care of us during our flights. He is really good at his job and I would highly recommend him.
I'd say the biggest downside for me was that I paid $30 for pictures and only got 12 of myself and my dad. I can't even imagine paying that just for one person. If you do go back though, pictures are half price as long as you bring the USB. The overall experience was great, though I don't know that I'd do it again, as it was quite expensive.
