A weekend in London or any of the surrounding areas, at least people would have a choice of hotels rather than get stitched up by the limited number in Cardiff. I too have been to both, and yes the new Wembley is far superior to the MS which I thought looked rather tatty the last time I visited.
I disagree about the level of publicity if the GP were at Wembley surely Pearson could get some of the right people at Talksport involved, get them to run competitions for tickets etc.
