Had booked the Fast Park area, and arrived within 10 minutes if the time I had booked for, only to be told that because a large number of people had turned up 2-3 hours early, all the lanes were full and the drivers were stuck in traffic. We're were given an exit ticket and asked to park ourselves within the main area and keep our keys, thus removing all the advantages of Fast Park. The staff were very apologetic, and cost of parking still good value. Loved the idea and simplicity of Fast Park, but would suggest that some guidance is issued to customers on timing of their arrival, to avoid a repeat in the future.
