The other week there was3 big vans in the red long term so van are allowed in ok and two had people inside,as regards waiting maybe wait in the filling station near the roundabout
If you mean the filling station by McDonalds, then don't. They clamp people who cross from the forecourt to McDonalds and vice versa from the McDonalds carpark to the forecourt shop. Do not set foot off the premises if your vehicle is there.
There are a couple of laybys along the side of the airport that people park up at, if you come off at the Ballymun exit of the M50 and take a left, then a right at the traffic lights, you'll see them.
No dont leave the van stay in it ,if your waiting,I’ve did it in cars,
Not sure I'd stay there overnight, but some might. It'd be a bitch of a walk with suitcases too. Just for the convenience of the bus to the airport carparks, I'd use them for the pickups.
