It will definitely be the second night when you are in Coco Cay. It is never the first or last night and you are in Nassau all evening on the third night and they don't expect everyone back on board for dinner.

Thank you for the information,I have reservations to swim with the dolphins on the 27th at 3:00pm, it is a 3 hour program and we have the early seating which means I would not have been able to get back(6:00) in time to get ready and get to the dining room in time, thanks again.
