Used the Multi Storey car park, on trying to get out it didn't work again. It seems to not work everytime and it takes ages for someone to respond. They can never find your booking by the Car Registration number so if you use this car park make sure you have printed off or have the booking reference to hand when you go to exit. Everything about the airport is poor especially the £5 to drop someone off. The council should do something about it, its a disgrace.
