Stayed 4 days, super expensive. Car park (short stay) basically a field with fences. Had to trawl around for ages to find a space. When it came to leave, you have to go the the pay meter first, then exit through the barriers. Even then, the gate did not recognise my registration and I had to press the call button, which was eventually answered after about 5mins and the guy put the barrier up to let me "escape"!
BTW, it's some distance from the terminal, not 5 mins!
