I may be too late in answering this... but I took a cruise with RC and had a stop at Coco.. we did the jet ski excursion. I am NOT a swimmer. I was terrified the whole time we were out there. I thought we would just skim along the banks and such.. but nooooo.. we went full speed straight across the open ocean. I was riding with my husband who had never driven one before. Was NOT a good experience.. at the time.. BUT.. looking back.. minus the fear and terror and thinking I would die at any given moment.. it might have been fun.. We had a very large ray swim right under our jet ski. that was cool. and it was beautiful... but honestly.. the best time I had on their island was just laying in one of the hammocks.. which cost NOTHING!
