The counter check-in was easy and pain free (add first up-sell), and the girls were polite and informative about the experience. We had some time to watch other guests and the instructors work in the tunnel while we waited before we got our gear and were assigned to Mike as an instructor. Great job Mike! We finished with the initial two flys and opted for one additional fly each, add second up-sell. This was worth the ten bucks as we got a little more freedom to move in the tunnel and learn additional technique from Mike, as well as the instructor working the control board. Afterwards while we considered bringing our young children to give it a try it, we chose to buy a package for returning flyers, add third up-sell. The up-sell is part of the business model, but at no time did we feel pressured. The only negative were young kids running around unsupervised throughout the waiting area, playing tag, and walking on the seats as their parents stood in an adjacent room eating birthday cake.
