First welcome to cruise-chat. I checked and it seems that Blue Lagoon Beach is still closed. I do not know if that just means that beach or all of the beaches on the island are closed. There are 2 lagoons there and lots of hammocks. It is still a nice place to visit. Unless they recently changed the deal you could just go to the island without doing the Dolphin Encounter. You will have to pay for you food and drinks though. BUt remember I said unless the rules have changed.
