I managed to get 4 together but only in the Upper Main Stand, there were only singles and the odd pair left in all the other sections by the time I was in. (Did have 4 selected in the Lower Main at one point, but someone must've snaffled one of them before I got them in my basket, argh). There also didn't seem to be any general admission/pitch tickets left, which seemed very weird? Maybe just something wrong my end there as I already had 4 in my basket, so didn't hang around to investigate further.
That was the Saturday, guess it might still be better for the other 2 days?
