Hi everyone. I'm a new AP and tomorrow we're taking a trip down to MK. This will be the first trip to trade the certificate for the real passes. Parking is free with the AP so what do I do when I get the the parking booth? Do I go ahead and pay and am then reimbersed? Do I show them my certificate? I'd just like to know what do ahead of time so I don't get there and look like a jacka**. I'll just look like that here. TIA
