We did the dolphin swim in Cozemel, summer 03. Yes, they do have lockers and we used them. We did not have any trouble, but you would have to decide for yourself if they are for you.. A lot of people were using them. I didn't hear of any problems myself.
We did take an underwater disposable camer and got some great pictures.
Formal night is usually the 2nd night of the cruise on a five day and the 2nd & 6th night on a seven day.
