The skinny on the increasing popularity of nude resorts

Vacationers this summer report that they are opting to travel to nude resorts rather than pay extra to stash their clothes in an aircraft's cargo hold.

Destinations where clothing is optional are riding such a wave of new-found popularity that online travel sites are openly embracing a term once reserved for people who spend their time promoting nude recreation: "Nakation."

In a recent online survey conducted by TripAdvisor, about half of the 22,091 travelers interviewed said that they wouldn't be shy about stripping off their swimsuits at the beach. This compared to about 31% of vacationers who said last year that they would visit a nude beach.
