This is a great port. Easy to find a tour once on shore, and easy to tour the entire island and have some beer and beach time. Since I snorkel, would highly recommend it here. Many islands are no longer "good" snorkeling due to hurricanes, etc, and Cayman and Cozumel are still very good. The trip to the "rays" is a good one to do once, but you can also walk off the terminal and go left to Eden Rock, or to the right for Callis shipwreck and cheeseburger reef....really easy if you have your own gear.
