I put 'drop off north terminal' and 'pick up south terminal' your site gave me a number of options and I selected one called 'valet'. Not only was my car at the north terminal when I arrived, but 'valet' did not mean clean. Presumably it was in the American sense of the of the word. But it was simply parked in the north terminal short stay carpark which is hardly 'valet'. Awful experience after a long flight. Absolute waste of £85 for four days of parking. I had used Airparks a number of times before and forwarded Airparks details to a number of my colleagues. It's unlikely that I'll use airparks again and have told my colleagues of the bad experience...
