This year Emily asked to have a group of friends join her at Skyzone to bounce on trampolines and scale climbing walls. And to have a disco party. And to have a sleep-over. With all 7 friends. Somewhat naively we said yes. Skyzone was great fun, lots of bouncing action then everyone had a go at climbing the walls in Skyclimb. Back at the house we fed them pizza before putting on the disco lights. Finally they settled down to sleep on matresses on the floor of Emily's room. Or at least some of them did. Some of them were still awake when George and I got to bed...
