F1 parking pass - not collected

[obn_ben]

Hi,

I've been trying all morning to get through to Silverstone to discuss parking without success. Having bought weekend tickets and a parking pass they arrived while I was on holiday and were returned by the courier company before redelivery could be made. I decided rather than risk another failed delivery that I would collect them from the circuit on Friday. Does anyone know or have experience of arriving at the circuit without a pass? I'm hoping I can get in with just the booking email

I assume traffic will be pretty heavy over the weekend. Is there much difference between M1 and M40 routes from London?

Ok thanks for all the feedback
