Made mistake of trying to pre-book a full day for less than a day's use. Costs for over running pre-booked time are so punitive I wanted to avoid over run. Unfortunately I ended up paying almost twice a much as I needed even after "discount". Regular user of this airport and not uncommon to find distressed lone female passengers in tears as car park attendants ruthessly apply short stay prices when over run occur. Recent cost changes mean short stays of less than a week at the long stay car park are now very expensive too. Overall value for money and flexibility is very poor
