>>There is a Freestyle Sun Deck on most NCL ships where you can go topless
Topless and nudist are normally 2 different people.
Sauna - "girls " and boys" are together and naked (most of those people are not nudist)
One use Sauna in Germany normaly only naked, any clothes are "verboten" in any
But AIDA have a separate nudist areas on the deck (for people of any age - for children too) -
there one can be naked or not , or topless.
But "normally" nudist have no clothes at all.
