Had to pass on a couple of seated tickets a few weeks ago. Our son is going on Saturday and his mates parents couldn't make it. We were tempted but the overall cost of travelling etc and the hassle of getting someone to look after the younger kids was too much. We saw them in Teignmouth last year, which was fantastic.
I'm not a fan of the acoustics in the new Wembley stadium compared to the original. Saw the Foo Fighters there and it was acoustically awfull, and the support bands were inaudible. I gather it sounds better on the ground, so good luck who ever get's them.
