My OH rang the number on the letter which came with the pass, to try and clarify the situation.
The person rang back at about 4pm.
The two car parks off Gloddaeth will be closed to visitors and the only people allowed in there will be local residents who have one of the passes. They will be manned by stewards and it will be first come first served.There will not be a charge on production of the pass. As I type there are a few vans parked outside which have been here for a day or two. Let us hope they are shifted by the 6am deadline or CCBC will have a busy time !
