We are coming out to Orlando at Christmas. We have done the dolphin swim at Discovery Cove twice now and wasn't planning to do again this time. However, DS has now said that he would like to go back just to go in the aviery and swim with the fish, not fussed about the dolphin swim. I have been on the website for DC but cannot book 3 non-swims, does one person out of every party have to do the swim? Any feedback gratefully received.
