Great idea, one slight problem it doesn't work. We were greeted by only one working camera booth, a massive queue at the reception, because one terminal was out of action, the booking in system was so unintuitive that it took a member of staff on permanent duty to help us all get cars booked in, It all took so long that if it hadn't been for a flight delay we would have been struggling to get to the gate. The return journey was no better an experience numerous of us returning to find none of our keys in the system, and no one on hand to help us. It took a hunting party to find someone who eventually helped us out. This wasn't fast park the poorly prepared technology behind this made it more like 'Farce Park'.
