We did the mangroves kayak trip. It was absolutely wonderful. You could have done the tour with an additional beach stop, we did not do it, however the beach was really nice and we wish we had. Other people in our party did not do a planned excursion and they said there is really nothing to do at this port, so they would recommend picking an excursion through the ship.
No cruises added
The water was very clear and the island was clean. The was a nice buffet on the island and good music to listen to throughout the day. It was very relaxing. Get there early though to stake out your spot on the beach.
Water isle bike adventure was really nice. Downtown shopping also had some great finds.
