Totally high cost of parking spoils experience. When trying to decide which parking area to book not easy to compare locations. Having previously parked at Stansted had rough idea of where particular park is located so fairly easy to arrive. Number plate not recognised but call for help did quickly opened barrier. Walk from Yellow park to terminal easy and quick, prefer close proximity as returning alone late at night. Exiting out of yellow park another matter, eventually ended up at an exit but again barrier not automatically opening. Had to call help again, fairly quick to get barrier open. Apart from cost no real complaint.
