Hi sambatc - was the most frustrating thing in the world..I ended up in both the long stay/short stay car parks, building sites, housing estates etc etc - but i just couldn't find the new NATS building. My sat nav never registered the street or post code, so that was no help - and when I went in to the airport to ask for help, they sent me to the OLD building...which wasted most of the time. Really really disappointed, but it was my own fault I guess...however a nice wee sign post would have been pretty superb !
Cheers !
