We did the dolphin encounter on the 10th of February and it was great! I would definately do it again! the boat ride there and back was very entertaining, there is a live band on board and they do lots of dances including the limbo! The beach was, in my opinion, very clean and there are lounge chairs and hammocks, and you can rent floats and things. There is a lunch provided and it was very good, you have a choice of hambugar, hot dog, chicken, ribs and you also get 2 drinks included.
As for getting to the boat in Nausau, i have heard alot about the hasseling of hair braiders, I had no problem, yes there were about 20+ that approached us (both DD and myself have very long hair) but a simple "no thank you" was enough and we were left alone. We also went to the straw market, I thought it was fun too!
