Christmas 2018 takes a twist – and quite a few turns – at the ArcelorMittal Orbit. The UK’s tallest sculpture houses the world’s longest tunnel slide, down which (sober) party guests are invited to take the plunge. Exclusive-hire packages cover use of the slide, as well as seated dinners or drinks receptions with bowl food. DJs are also included, and the venue is licensed until 2am. If further entertainment is needed, a dedicated events co-ordinator will help you choose.
