Freikorperkultur (FKK Bereich) fore-located Nudist Deck. All AIDA ships have a generously-sized outdoor area where naked passengers can enjoy sunbathing protected from the gaze of curious suitors. The special FKK area is located forward on the ship's top-deck. In cruise ports where the country's culture doesn't allow nudism in public spaces (for example, Muslim countries), the AIDA cruise ship's FKK deck can be accessed only in swimwear. Unlike most AIDA cruise liners, AIDAcosma's FKK deck has no whirlpool (hot tub).
