Sorry to say that Akumal is not so much the laid back place it has been in the past. With all the boat snorkel tours coming into the bay constantly you need to be in and out of the water for good snorkeling before about 9:15 in the morning. Otherwise you just have to deal with being run over by hordes of inexperienced snorkelers harassing the turtles and everything else in their path. During the past week I figure the average number of snorkelers in the bay at any given moment had to be close to 75. Something's got to give or the place will be a wasteland in a couple of years. CEA (the ecological group there) and the Akumal Council are trying to work something out, but that sort of thing takes a lot of time in Mexico.
