This is the first time in 7 years that I'm in a position to help other people without having to scramble for our own tickets; also someone else got our tickets in November so I feel I need to pay it forward. After mulling it over I've concluded I can pay if I get through tomorrow, but can't cover the cost of 4 tickets for Sunday. If I'm lucky enough to get a booking page on Sunday I'll need someone from the group to give me card details and verification code if required. Once you're through to payment the tickets are held for 5 minutes, which should be enough time for details to be passed on and for me to input them.
Good luck everybody, and remember to double and triple check those reg nos and postcodes!
