We took our family of 5 to this attraction. My boys were age 5, 10 and 13. They do a video instruction and your flight guide give you additional instructions. Your flight person stays in the tunnel with you the whole time. I was kind of scared but once I went into the tunnel it was not scary at all. Everyone in the family loved it. It is a little pricey but not too much out of line for a special treat. (especially if you are paying for the food at the theme parks!!)
You are encouraged to book your appt ahead of time, so you just show up, head up to watch the video and fly.
They do have notices posted that if you have ever had a dislocated shoulder to let them know. Not really sure why, but if you have had one it might be a good question to ask.
