We didn't do it but, we did watch 2 people for at least 1/2 hour in the water with the sharks. We had our first lunch at Sharks Underwater Grill (The dinning area has several large viewing windows of the Sharks that you can see when you go through Shrak Encounter) and there is a shark cage that appears on the right side of the dinning viewing windows and slowly moves to the left side on a rail system then returns to the right side again. If thier family had their camera setup properly then they probably got many shots of thier kids waving to them from the cage with all the sharks and fish in the water. I dont know age/costs for this experience but it looked fun to me - and the idea of the family eating and watching thier kids while they swam with the fishes seemed like everyone had something to do instead of waiting on each other.
