We are at the Point Village right now and snorkel that area almost every day. I can tell you that there is no debris dumped in the ocean opposite the Royalton construction and the reef has not been destroyed, so let's put that to rest right off the bat. I thought that the OP just wanted information about where to snorkel. Pretty sure they don't need to hear about untruths and half baked ideas.
Nancy Turner Brown, what I would do is walk the beach from RIU as far as the construction fence at the Royalton. Start snorkeling from there and head to towards The Point Village. Tons of angle fish, trumpet fish, and a few rays. Right at the point of land at The Point Village is a school of medium size fish numbering in the 10`s of thousands. They swim like a wave or a waterfall. Kind of neat to watch. As the wave of fish swims towards some coal sticking up from the bottom and the wave opens up, swims around and then closes on the other side. Also RIU has snorkel boat trips to the reef every day. Kinda lame though, snorkeling with a large group.
