Hello, thanks for your interest, we are in the busiest and most important area, there are many bars and restaurants, so there is music, but only at authorized times.

I did not sleep there so I am not sure what to say. I think this is better question directly for them.

I am not sure about that and I did not see anyone there doing it. I can tell you that while I was at Casa Teka cenote which is on Tulum beach road and very close, that a couple that "forgot" their swimsuits were told that they could swim without. This cenote is beautiful and you have access for the food/drink cost of $30 or $35 USD. You can check it out online at Casa Teka. Hope this helps. I had a fine time with my clothes on though if that is any consolation. Have fun and sunscreen up if you go nude fo sho. No suncreen in cenotes though!
