I've received several calls, too. No message(s) left, however.
Why would a nudist resort (appropriately named "hot" in Spanish) be cold calling? From a cell phone??
I've visited there before (am a long time AANR member), so perhaps they have my number on file from prior visits. But that was before they changed their "orientation" and affiliations . . . I / we won't be returning, even though it is a very upscale niche resort.
Perhaps they're trying to sell some remaining building lots? Sorry . . . I'll work on tan line elimination from AANR-affliated clubs.
