did the blue lagoon back in 2000,had a good time, snorkleing isn't all that, you swim in a small lagoon, not the ocean. but was still worth it. nice lunch, steel band. if you feel like exploring you can walk the length of the island and dip in the ocean along the way,wife and I did, left the boys back at lagoon, no problems. don't think it would be worth the trouble to make arrangements on your own, pretty involved.
