Will be staying at RIU Palace Mexico (Playa Del Carmen) 3rd week of January 2011. Looking for beaches where nudity or at least toplessness is allowed. Are their public beaches that allow it or do we need to look for private beaches? I have heard that some of the resorts allow it and if so what are some of those resorts. Hidden Beach Resort was mentioned but I can't tell how far that is from RIU Palace Mexico (Playa Del Carmen). Thanks for the help.
