Used it last Wed, May 8th.
Stayed overnight, very quiet, about a dozen vans there.
TT satnav directed us to the wrong side of the fence, and there's no gate to open and go through, but we managed to follow our noses and found it.
I would suggest aiming for Cite Europe, and then picking up the camping car road signs for the aire.
There's a bit of construction work going on in the area which might explain the unexpected fencing.
