Swingers and Sinners — Thursday play party

Swingers and Sinners runs a swinging play party for sexually adventurous adults every Thursday at The Central Station on Wharfdale Road in Kings Cross, from 1.30pm to 7.30pm — a large open-plan basement eight or nine minutes' walk from Kings Cross station.

The organisers work to keep the ratio of men to women close, through their pricing policy and their contacts in the swinging community: they say twenty or more women are present at a party and that they strive to keep the male-to-female ratio under three to one. Their What To Expect and FAQ pages are the place to decide whether the party suits you before coming.

No booking is needed: the organisers say plainly that you turn up and pay on the door, and both cash and card are accepted. Entry is free for single women and for mixed-sex couples. Admission prices for other guests are published on the organiser's own site and are indications — confirm them at the door.

The same organisers run daytime and evening parties at the same address under the Bi Fun Club name.
