Go to their website,
https://www.iflyworld.com/orlando/ for session lengths and prices. They have everything from 2 minute sessions to renting the tunnel for an hour. 2 minutes doesn't sound long but it is a great experience. Now that our son has been doing this for years we rent the tunnel just for him for 30 minutes and he works with an instructor on tricks and different ways to fly, i.e. belly fly, back fly, sit fly, etc. He would rather spend a day here than at any park. I don't know how he stays in the tunnel for so long. When I used to fly, a few minutes was plenty, but he goes for 30 minutes and comes out exhausted but smiling from ear to ear.
