I'm not doing EOD colour coded at the 6 Days, but still had a need to book a parking ticket, training maps and camping and that isn't possible - you can only order those if you have an existing entry

I have sent a query to this to info@6days but they've had it almost a week now so I'll have to sort out training maps at the Ticket office in any case, so please message me if you can oblige (just in case they've sent a reply by then).
Cheers
JK
