OMG it was so fun! We were taken behind the scenes and taught how to behave like a CM as guests don't know you aren't CMs. Planned our our time, learned about the tanks, fish, etc. Then we put on shortie wetsuits and met to go to the top of the tank platform where they had gear all set up for us. We got to interact with the guests watching (really hamming it up), got "nibbled" by fish (can't remember which ones), swam around for what seemed like minutes cause the time just flew by, and just had a blast.
Also if you have fam in the restaurant the underwater videographer will get them and you together on both sides of the glass for pictures. I'd do it again in a heartbeat! We got a tshirt (cool one), certificate, etc. We didn't buy the video as each person was only on it about 2 seconds total and the rest was PR for Dive Quest. It was fun to watch (they show it to you after the dive) but maybe a different videographer would have done better. All in all, it was truly a magical experience.
A must do imnsho!
