Is nudity allowed? Can I be nude anywhere in the resort? Do I have to be nude in the "nude" area? Can I be nude in the "prude" area?

Yes, most of the resort is clothing optional and sex-positive. There is also an area of the resort designated as "nude". 

The resort asks that you (at least) minimally cover up in lobby and most restaurants. Of course  that doesn't even mean you need to put on clothes…just wrap a towel around yourself and grab some food! Or better yet, throw on some sexy lingerie that barely covers your goodie bits…just because you can't be nude doesn't mean you can't be scandalous. 

Note, in the Nude beach, nude grill, and nude pool area (which is located at the far-end of the "nude" side of the resort) you MUST be nude. The rest of the resort is playfully called the "prude" area where clothing is optional.
