My son and I did the Dolphins in Depth program at Epcot 2 years ago because they had a DVC discount of "buy one get one half-price". It was wonderful. You spend some "class time" learning about dolphins and see all the behind the scenes stuff at the living seas. You put on wet suits and spend about 30 minutes in the water with the dolphins (but you don't actually swim with them). You stand on a platform in about waist deep water and the dolphins come to you. You pet them, get them to do a few tricks and they take a picture of you hugging them. We were thrilled with the program but the Discovery Cove one looks like it might be better for interaction with the dolphins (it is also more expensive I believe). If anyone can post both current prices that would be great.
