Generally a good service from using your Aberdeen Airport short stay car park. The price was on the high side. Main observation: After an easy entrance to the car park via the traffic barrier vehicle number plate recognition system, it was then difficult and confusing to follow the many different signs to the car park of my choice. I would suggest a "colour coding" system would be far more User Friendly. Another car in front of me also had difficulty in finding the long route to the short stay area. The traffic barrier is right beside the short stay car park but to gain entry I had to travel a long way around the multistory building to get access to where I finally had to park.
