Ami-Jane pit lane walk is earlier than lunchtime and they charge £12 extra per adult; Greedy FIA.
Make sure you are wearing your best SEAT Sport shirt and as many lanyards as possible and we might be able to get through via the Paddock
..... Look like you belong, wear shades, hold a walkie talkie and speak Spanish and just stride through just after support race cars are coming or going. I've managed it very time I've been to WTCC.
I might have a few items that would help you in my garage/wardrobe/cupboard under the stairs!
Another top tip....be angry and shout down a phone - people don't like interrupting shouty people.
