Nearly 250 people have qualified for a whoop n gloop on the Arsehole Terrace. When you add in Scam & Fam, plus the skeleton staff, and people can bring a guest for 25 quid so say 270 being generous.
Thing is the shared terrace is 2130 square feet, so 198 Square metres, that only gives a person 73 cms each! It is unlikely that they all come but throw in furniture, benches, plants etc that are already up there, then room for the champers and canapes either being laid out or additional catering staff to serve, it's gonna be rammed jammed like a sweaty school leavers disco with a gentlemen's pride stink bomb let off.
