I can't vouch for all, but at the Grand (inside the park area), there is an area that is set up with bouys - you can swim etc. within that area. Once outside that area, you are required to purchase the park day pass - that includes using the watercraft such as sailboats.I am curious if the hotel's that offer "shore diving" inform the diver about the rules or if the hotel (and several offer it) is far enough outside the protected park it doesn't matter. In other words how would a guest know if they were doing wrong?
Christi, do you know?
As an aside:
Last November my wife was learning how to sail a Hobi-Cat off of the hotel. They came upon a fellow attempting to snorkel out to the reef offshore. He was prime to get whacked by any one of the many dive boats moving up and down that area. No reasonable person would be on the lookout for a snorkeler in the water in that area! He was quite pissed off when it was "suggested" that he either turn back or get on the Hobi-Cat for a lift back.
