If you are just going to go to a beach club and hangout. Make sure you research between beach club and snorkel beach club. Basically the difference is
beach club = sand > water
snorkel beach club = sand > rocks > water.
Our first time(2012), our TA got us an indy excursion to Playa Uvas. We took a cab there. It was nice but to go wade in the water you are walking over rocks to get into a wading level. This place had some sandbags on the rocks to make it a bit less hard. The researching I've done, the snorkel clubs are on the western side of the island closer the ports and the beach clubs are more towards the southwestern end of the island.
