Merry Swishmus. The last Hellfire weekender before Christmas lands Saturday 19th December, 9pm till 2.30am: thirteen play areas, two dungeons with log burners going, two heated gardens, the grope maze, the Cage on the Stage, brick-oven pizza and a fully licensed bar. No rip-off prices. Single ladies come free on Saturday if you’re there Friday — and single gents, this one sells out, so book early.
