As in, you don’t:
Clothes will be strictly forbidden on the premises of Germany’s first hotel for nudists, which will open shortly in the southwestern Black Forest region.
Investors plan to set up a hotel catering exclusively to nudists in the picturesque Black Forest town of Freudenstadt, which incidentally translates as Town of Joys.
Guests will be required to remove their clothes at the entrance and must be naked at all times while on the premises, according to the strict house rules that have already been posted on the Internet.
And you will behave yourself:
The rules state that all guests must put towels on chairs and loungers before using them, that there be no sexual harassment and that all sexual activity in commonly accessible rooms is strictly forbidden. People who break the rules will have to put their clothes on and leave.
You’d be thrown out of an American naturist resort for similar offenses, so this doesn’t strike me as particularly harsh.
