Given there are a number of different car parks in the airport grounds the directions to the different sites are very poor. We ended up having to reverse against traffic to avoid entering the multi story parking. Luckily there was an attendant on site, he happened to be crossing the area, didnt see annother the rest of the time, to help us. When leaving we drove to the exit hoping that the anpr would recognise our pre payment - which it did - as there was no one to help in sight. Having said that the location is excellent, with only a short walk to departure - and the discount for pre booking makes it excellent value.
