All aboard The Jewel of London, one of the largest party boats to grace the Thames. It’s Halloween and you know what that means: ridiculous outfits and non-stop mayhem till the sun threatens to come up. DJs will keep the tunes pumping as you cruise the river, then it’s on to the club to keep drinking and making merry till 7am. Have you got what it takes to survive the night? Over 18s only, ID required. Please arrive on time or the boat will leave without you.
