My DD19 did this in early December. She thought it was great, but she's also in college for marine biology. The tour began with some behind the scenes of the Manatees and Dolphins. There was also some instruction on how to use the scuba equipment. You don't need to have certification for this tour. You stay buoyed to the top of the tank and sort of float around. You are asked not to touch any of the sea life though. She also got a t-shirt and photograph in her wetsuit. It did take up about 2 1/2 - 3 hours of the day.
