We were scheduled for 8am, but it was canceled for lack of people. We were then put on the 10:30 no lack of people 60 on a boat exactly why we booked the early trip. Unless you book a private tour outside companies are required to send you to your ships site for reservations. This is more like a private cruise line owned island.
Drove up to the top of the island for awesome Banana Daiquiris. Got to see all the bays and hot spots of the island. Two hour tour and when you are done you can either be dropped off in town or back at the cruise ship. Definitely worth the $25PP
