In 2008, the snorkel gear was very basic, no special lenses. Also, you can only rent during the time the snorkel shack is open....If you bring your own snorkel gear, you can snorkel anytime and in other spots than the snorkel shack...Although the reefs by the shack are good....further down the road closer to the restaurant and nightclub is where the tourists from Aquaworld snorkel...I did that area one day and it was also very good...so if you are not really a snorkeler the shack is great if you are experienced , bring your own equipment....just my thoughts
