We've been twice before, both times based on the large pontoon, with buffet lunch etc.
I've noticed a few people talking about going there, but not based on the pontoon. What is the price difference? And, for anyone who's done both, is the experience as good? Can you snorkel next to the pontoon, or is there a barrier to keep you out? Is the marine life as good outside this area?
Any drawbacks to doing it the cheaper way?
