Most beaches in the Carribean have wave runner rentals right off the shore. Everywhere we've been you have to be 16 to drive one. Be careful though as some people who are renting them aren't licensed to do it. That happened to us in the Bahamas. My daughter was out on one and the people we were renting from weren't licensed. The police boat came out and took her off the jetski and confiscated it. The people that were renting them jumped on the ones they had and took off.
