My mom and I did the Dolphins in Depth tour last August. It was about 3 hours, maybe 2.5 really. Of that time only 1/2 hour is with the dolphins. You get to pet them, do some hand signs that are used in training them, and you have your picture taken while holding one. You do not get to ride or swim with them. Other things you do: watch a film on marine mammal safety/law. Put together a dolphin puzzle, hear about what food they eat and how they’re trained. You do go on-stage and see some of the exhibits in the Living Seas with one of the instructors and get some interesting info at some of the tanks.
Alot of the experiences has to do with how many people are in the group (I think they take 8-10 people total…we had a full group), how crowded the Living Seas are, and how much the dolphins are interested in interacting. We went, apparently, when the dolphins were acting a little weird (according to their trainers, we all thought they seemed normal) and were apparently a little more…shall we say frisky than usual. So the trainers were extremely cautious about how the interaction was done.
It was a great experience that I really enjoyed doing.
