There's a wealth of ways to see London, but after dark one of the greatest experiences has to be taking in the capital by boat. With a cash bar serving drinks at pub prices, you can watch the nightlife glide by with a beer in your hand. There’s also a hot buffet to enjoy, a resident DJ spinning classic anthems and admission to Opal when you reach terra firma. Ain't no party like a Thames riverboat party. Over 18s only. No all-male groups. Boat returns at 1am.
