After booking on-line, it was an easy process of simply parking in the secure long stay car park and then taking the shuttle bus to the main terminal. The car park is well used, but there are adequate spaces further toward the back of the car park on busy days. The busses are rotating constantly, so even if you just miss one, another comes along within a few minutes. On return, the opposite procees applies - shuttle from the terminal back to the car park. There are stops around the car park, so you just hop off closest to where you parked. With the number plate recognition system, departing is as easy as popping your ticket into the machine at the barrier and driving off. No problems.
