The online booking process was straightforward. There was plenty of space in the overflow parking section but, unlike the main parking area, the zones don't seem to have been given a number or letter. Useful tip: note the nearest numbered bus stop as a guide to the location of your car. As on a previous occasion, my car's registration number was not captured by the camera on entry and so, on departure from the car park, I had the tiresome and time-consuming experience of having to reverse back from the exit gate, park and go into the office to have my booking checked and my exit cleared by someone on duty. One of the airport buses was parked in the space outside the office, leaving limited room to park.
