280 people in RS in the UK seems like a high estimate to me - three times I've been, and each time although the space looks so tiny to me I also thought it's really just a few people.
That's what it was at the O2, we asked security. Other arenas were smaller
Oh, I see, I was in general standing there, just had to snatch cheapest ticket for my additional London trip, and I did think the difference between that and RS didn't seem that great anymore. LOL, glad I went to RS in all the smaller places, meeting Josh felt like hanging out in a lounge, it was that relaxed!
