My kids did this last year and they just loved it. The adults get to do a liitle more with the dolphins than the kids. It is a well run program but you need to get lucky to get a reservation. If it's still run the same you could only make reservations three days in advance, no earlier. We made them through our hotel concierge. The only negative I found was that the water you swam in seemed dirty, but I'm pretty picky. There was a shower for everyone when you came out of the water. We did the one at the Navy Dockyard and it was in August. Hot hot hot! Make sure if you do it you have someone to take you pictures! They will take one for you but if I remember correctly it was very expensive.
