Worth mentioning that if you haven't swapped your seats yet, you can just get up and walk down the stand and find an empty one on the night. The whole L2 should be open. You will probably have to go up the spiral from North/CB corner to CBL3 and back down again into East/CB corner, not the opposite side as VR fans will be there..... but the whole stadium can be circuited internally in under 15 minutes so it's no biggie to do it at half time if we're shooting that way for the second half (hope they've built this into the plans).
Me and bloovee regularly used to do this in quiet cup games, just for a bit of a change. And of course, thousands did it on the Kippax.
We might well have "our own seat" and they can make you sit down but they can't make you sit in your own seat.
We'll be in South/CB2 corner for this (comfy seats) so might move along if it looks like fun.
