I have my tickets for the British GP on 20th July, but now I have to
work out how to get there. What I have found on the Web is that I
should be able to catch a train to Northampton or Milton Keynes and
then catch a bus. What I can't find out is whether it is possible to
pre-book tickets for the bus. Can anyone who knows please tell me
what the answer is, or point me to the right information? It seems
impossible to phone anyone to get an answer (nothing but engaged
signals). Thanks very much in advance,

Cheers,
Tony.
