There aren't any trains and it's always a pain for these late Sat matches.
At the moment I'm waiting on a Spurs fan as they've got a charter train going up from Milton Keynes (maybe Euston) before and after the match. If you've got a Spurs mate who's going and you don't mind being on their train, that might be an option.
If I can't get on that, I'll probably be driving from Windsor. If I do, might be able to offer you a lift. Will post here when I know.
Was going to stay for the weekend (usually do) but the hotel prices have gone mental.
