General Admission is standing. (GA) Gold circle is the best to be, this is also standing and is a cordoned off section right at the front. I have been to a lot of stadium concerts and am always ready at 9.00 a.m. on the dot with browser windows open with all the ticket agencies. As yet I have never had a sniff at Gold Circle. To me they are the Holy Grail, I just think it's down to luck as I couldn't do anymore than Im doing.
Good luck tho for Friday. It will be crazy I can guarantee!!
