Well, I've given it some thought, and have to say I'm mildly disappointed in the move to lock up the SFS as the venue.
Partly because, coming in from the west, its nice to be able to take the short journey to Olympic Park. Even though the atmosphere there is generally shit (the Final last year excluded, obviously) and the local facilities are not up to the standards of the Beerluminati.
I live near a train station so I can get in and get out again with reasonable speed, and don't mind the walk to the stadium (fuck buses, seriously).
But the facilities inside the SFS are shit. The concourse is poorly lit, and too narrow for a crowd, while the old seats need replacing. I generally don't move from my seat for the game unless I'm desperate to piss, and don't even bother with the shitty "beer" and "food" they "serve".
Hopefully part of the deal is that they actually put enough fucking staff on at the games, and upgrade the lighting around the footways to suit. Some decent beer wouldn't hurt, either.
