I believe you will be able to take a taxi as you get of the ship to the Ferry Boat dock. The boat ride to the island is about 35 mins or so. My DW and I did the dolphin swim last year on our 20th Wedding Anniversary when we were staying at the Radisonn Cable Beach. It was truely one of the neatest experiences in my life. My daughter and the daughter from the family we're going on the Wonder 6/29 cruise with are going to do the afternoon swim. It's a real treat!
