The parking site is huge and although Pre-booked you don't receive a designated parking space, not even a designated area, which are marked out alphabetically. This resulted in spending some considerable time driving around looking for an empty bay. The other issue was the areas are alphabetical but then when you get on the bus that shuttles from the airport back to the car park they say bus stop 1 bus stop 2 etc. The parking areas are so large you could be at up to 4 bus stops per an area. This is not at all helpful! The attendant at the office you had to visit get your ticket validated when you had pre booked and paid was most unhelpful and rude.. There are better organised offsite parking facilities around the airport which I have used in the past and will return to using.
