We opted for the self-guided fun by renting a tandem kayak.
It took about an hour from when we arrived to when we got to the beach- by the time we did paperwork, loaded up, and did orientation. Unloading was really quick though.
Bring sunscreen and sandals (not flip-flops) for unloading and loading the kayaks- and lots more to reapply when out at sea.
Everyone was very helpful, knowledgeable, and the time at the island itself was absolutely amazing.
The waves were a bit rough the day we went out but overall I would recommend this experience.
