I'm sure its been discussed, but I figured it quicker to just ask...
1) Has anyone snorkeled right there at the resort? If so, is it decent?
2)Can you do it naked?
3) can you rent gear at resort or is it bring your own?
We don't intend on leaving the resort to go on a excursion, but wouldn't mind playing around in the water while there.
I've snorkeled in the resort, while naked in the hot tub, I brought my own gear (it's always with me)
As for what you are really asking - I think there's a place where you can set up excursions (off site), not sure if they have any rental gear but I've never seen any sign of it. I would think you could bring your own and snorkel naked right off the beach with no problem. Not sure how much you would see, but that would be a good way to do it for a while easily without having to go off site.
