This year, all the cool kids are partying on boats. And this isn't any old boat either, it's a replica 19th century Paddle Steamer with multiple stages. Haunting beats and wicked drops are all you need to get dancing as you cruise past the Tower of London. Plus as this spooky sail draws towards the witching hour, there's a secret after party to get on down to as well. If you dare. Over 18's only. Arrive at Pier 15 mins before departure. Fancy dress is optional but very much encouraged.
