2006, stayed with relatives in Fleet, within earshot of the airfield but, on the Wednesday, with no available transport and too far to walk, had to drive.
Left the house at 08.50 and due to traffic restrictions had to follow a particular route almost 3/4 round the airfield the wrong way. Arrived at the nearest available car park at 09.40 having queued on a dual carriageway in the wrong direction for 25 minutes before being directed around a roundabout to queue for another 15 minutes in the opposite direction to get into the car park.
Basically a 10 minute journey took 50 minutes and that on a trade day.
They seem to change the traffic arrangements every time so planning the route you took last time won't always work.
