The terminal surface parking is very convenient as next door to the terminal. Strangely it becomes more cost effective for a longer stay. (4 days or more) than just one night. The number plate recognition on arrival works well. We had some confusion on booking as I thought I had booked for terminal surface and multi-storey, in fact you book for either or, so worth double checking which. Signage into the multi storey a bit confusing first time as there are two entrances. We had to park in the open air right on the top although there were lots of empty floors on the way up which were all closed off for some reason.
