Secret Underground Dark Sins Hotel Take Over 2026

Dark Sins is a Secret Underground hotel take-over — the organiser books out an exclusive hotel and runs the whole building for the night. This one is on Saturday 12 December 2026, 20:00 until 03:00, and it is billed as an exclusive mask event in a black and red edition.

The location is withheld. Secret Underground publishes only that it is a secret exclusive hotel in North Brabant; the address goes to ticket holders. We have not guessed at the town and there is no map pin on this listing — a pin in a place the hotel may not be is worse than no pin at all. Rooms at the hotel are booked separately, through the same ticket shop, and the organiser marks them as limited.

The dress code is strict and checked from the moment you arrive: masquerade, lingerie, a touch of kinky, in red and black. Men are asked to stay in long trousers until the end of the night. Bring your own mask for the first few hours — the masks are the point of the format. Drinks are bought with tokens rather than cash at the bar.

Two house rules are worth reading before you book: no phones, and no single men — entry is by couple ticket or lady ticket only.

Tickets are sold through Weeztix in tiers. When this page was written the early-bird couple ticket was advertised at around €119.95 plus a service fee and had already sold out; a regular couple ticket was advertised at around €129.95 plus fee, and a lady ticket at around €54.95 plus fee. Treat all of those as indications — tiers move as the date approaches and fees are added at checkout, so confirm at the point of purchase.
