Have they? The gits.
In which case i'd just wait at the hilton and wait for them to land. And get them to meet you there.
Get yourself a maccy d's and sit in the car park there. Is only a minute drive to either terminal from there.
But don't wait too long in the maccy d's car park either or you'll get fined... (not sure on the maximum stay, but there is a sign up in the car park and a friend of mine had a fine in the post for staying too long whilst waiting to pick someone up)
yep, tis drop off only, abused but swarming with attendants
They can't fine you if you're sat inside drinking a coffee purchased from them though? Then you just get up and leave when you get the text.
