On arriving at Newcastle airport, I dropped my wife and 2 friends off at the short stay car park, whilst we unloaded the cases for our holiday and paid the £2.50. They took the cases whilst i parked the car, which i proceeded to do. Collected by a nice friendly bus / coach driver. On our return my wife and friends collect the bags and i hurried off to the coach/bus to be transported to my car(again another friendly driver). On collecting my car, presented the ticket to machine which was refused, barrier failed to raise, tried again nothing, I returned to the manned station / reception to be told that because id drove into the short stay car park the camera had recognized the number plate and it had registered me entering and exiting twice in my parking allocation that's not allowed. He then done something to my ticket and i went on my way to the barriers, only for them to fail to raise again. i left the car at the barriers, walk back to the station whereupon the gentleman came back out the the barrier and raised it with a swipe card. The speed of which I'd had hoped never materialized. Overall its a great system, but driving into one car park and dropping off suit cases and parking in another shouldn't cause that much of a problems!
