I had one previous indoor flying experience at one of the oldest locations in the states. The technology, training, and suits were definitely dated compared to iFly! For starters, all of the staff were great and helpful. Our trainer was a blast to work with and quickly discerned our skill level to assist in coaching us up to a higher level.
I paid extra for the "high flight" which is basically the instructor taking you for a ride up higher in the tube. It's more fun that words can express! I highly recommend this experience to anyone. It's safe, clean, and a ton of fun.
