My BF took me here as a surprise for our anniversary and it was definitely a nice (and interesting) surprise. We were booked for 7:30 pm on a Saturday for two flights, which includes a high flight. This means that on the second flight, your instructor will take you up to 14 feet. Don't worry, an instructor is with you at all times for both flights, and they show you exactly what you need to do before the flights. They provide the suits, helmets, and goggles. You just need to make sure you're not wearing any loose items that can come off (i.e. jewelry, watches, flip flops, etc.)
Since our time slot was at 7:30, we thought we would be in and out by 8. However, we didn't finish until past 9. It was a lot of waiting around since we had to wait for other groups ahead of us to finish. Each group has about 12 people, and each flight lasts 30 seconds. We waited until 8:30 until it was finally our group's turn. That being said, just make sure you're not in a hurry to go anywhere afterwards since you'll be stuck there for a while.
I don't know if I would come back. It was more of a one-time experience for me, but I definitely recommend everyone to try this at least once in their life.
Tip - you can't bring anything into the vessel, meaning no phones, meaning no photos (unless you have someone with you who isn't flying - they can take all the photos they want from the outside). But you can purchase a digital copy for $4.
