If you're not single this might be the weekend to take a strategic break, because only those without partners are invited to this lofty sleepover in London's pointiest landmark. This all-night event will involve a look at the night sky through a telescope provided by the Royal Observatory, acoustic performances organised by intimate gig experts Sofar Sounds, a midnight feast from Pizza Pilgrims and plenty more games and entertainment beside. VIP bell tents will be pitched on the highest floor of the building that's publicly accessible, and sleeping spaces on Level 69's viewing gallery are available for those not into glamping. Your sleep will be interrupted with hot drinks and breakfast as the sun rises over London's beautiful skyline. BYO sleeping bag and book in advance.
