"If your address isn’t UK, your tickets/carpass will go for collection."
Unless I'm mistaken, I thought you needed a carpass to get into the car parking areas to begin with. Don't know how that's going to be managed as going by the above, and probably slightly overexaggerating here, we'd need to queue to pick up the carpasses, then park lord only knows where, then to head back to PGA box office to queue again 🤔
