We did this last September. It is $160 per jetski for 2 which will easily hold an adult and child or two smaller adults. We reserved two as it was just my husband and myself and we each wanted our own machine. Neither of us had been on a jetski before. It was a blast. We left the beach and circle out around the ship and headed to a sandbar about a mile out where we beached the jetskis and listened to our guide who talked about the island, ecosystem, water depth, fish and sharks. I was in the back of the group when we left because of my uncertainty with the machine but near the front on the way back. You do go single file-they do not allow any going off by yourself. It was about an hour. We went in the afternoon at 2PM so we enjoyed the island and lunch first and had a sunny afternoon for our ride. It was a little choppy. I was sore the next day from the workout but we both enjoyed it. Expensive but I would do it again.
