I have used Plane Parking many times and I am always satisfied with the price and service provided. I commented to my husband this time that the ticket issued upon arrival did not have our car registration number on it. I just hoped that a) I was in the correct car park ( I know this is an irrational thought) & b) that I would not have a fee to pay for being in the wrong car park. Upon returning to the car park I presented my ticket to the machine and was denied exit. A payment of £250 was requested. This was a bit of a panic! I pressed the button to speak to someone who could help and I explained that a payment of £250 was being requested. I was duly allowed to exit without payment. Not a huge issue but something that definitely needs some attention. And please revert to printing the car registration number on the tickets. It would also be a good idea to have some signage on the side of the bus shelter at the bus stop for pickup from the airport back to the car park. The only sign is on the inside. Four of us commented on this.
