Very nice and helpful crew! Went during low season and felt that it was just enough people. Couldn't imagine the crowds (up to 500) during high season. Areas roped off for snorkeling: wide enough area to explore but still felt safe with lifeguards monitoring. Optional add-on experiences, ranging from diving to a helicopter ride, are very expensive. Total time on the pontoon is just over 3 hours, so snorkeling and lunch was just fine. Lunch is alright and had more variety than expected. Underwater cameras available for rent ($25-75) if you don't have your own. Overall a very wonderful experience! Tons of fun for first-timers and more experienced alike.
