The structure is very weak in favor of management convinience. It is very much a case of nonexisting customer focus. Around the fair ground, traffic control is pathetic. They spent millions on a system called MOVE that switches signs on and off but is entirely incapable of reacting to actual traffic conditions. The speed limit is set to 80 wether there is no car at all or a traffic jam.
Directions are misleading or missing.
They keep reducing the number of parking lots but build the train station miles from the fair-ground. And no zebra crossings for pedestrians. They have either have to walk miles to the next traffic lights or traverse the traffic flowing at high speeds. The list of management blunders goes on and on. I got the impression that the event got to big for the management to swallow.
