How to Map
Add a node to the centre of the swingerclub and tag it with amenity=swingerclub. You can name it with name=*.
Swingerclubs can be referred to as amenity=nightclub, but this tag should referre to discotecs and other forms of nightclubs.
Not to be confused with amenity=brothel - there is no paid sex in a swingerclub. There are sites named FKK-clubs or similar, that are not swingerclubs.
In a swingerclub adult people meet to have a party and group sex, usually they pay an entrance fee for drinks, food and using the facilities.
