I guess the parking is ok overall but there are one or two issues - large sections of the car parking area can be blocked off making it difficult to find a space - depending on how far you drove into a parking zone, to get out, you can have a long drive back and forth along all the rows remaining in that block. The 'Exit' is not clearly signposted and there isn't a throughway at each end of a row, only every alternate, opposite end - hence the irritating drive back and forth - especially irritating when you are tired after a long haul flight. On the plus side - the system of paying in advance and number plate recognition at the barrier (albeit with a ticket issued by the machine at the barrier) works well and saves money - the buses are big enough to take nearly everyone waiting at the bus stops - at some airports you have to wait for the little bus to go round again - the buses go round frequently, or at quiet times, if not circulating continuously, will come immediately if you call using the telephone in the bus shelter - the drivers are very friendly - the staff in the office/cabin at the exit are efficient and helpful if you have to pay or sort out a problem. So full marks to staff and buses, the payment system, and entry & exit mechanism, but the design layout of the parking sectors could be improved, as could operation of the overall car park in deciding whether to open or close individual sectors.
