We had a kayak and a SUP on our last charter. Used each of them only once. Had 11yo, 8yo and a 6yo. We really found them to be a bit of a PITA. Heavy and awkward. Not easy to maneuver on or off the boat. The kids really jumped off the boat, played with the dingy and went snorkeling. They diddnt really need much else. The 11yo became our dingy captain and by the end of the trip he was zipping around by himself.
