We headed to an Aire at Abbeville that had been recommended to Club Motorhome but was new to us, also that it was a motorway Aire which we rarely use and don't generally advise the use of for well publicised security reasons.
Anyway, we hopped onto the toll motorway in order to gain access and were pleasantly surprised at the facilities provided. Free water, waste and EHU (albeit for the service point so long lead needed). The designated parking is along a layby-like marked off area but with a little searching there is a very nice picnic area at the far end of the facility for caravans which security staff confirmed was fine for us to overnight.
The service area has all the amenities that you would expect including free wifi. The walkway to the parking area crosses some water containing the friendliest ducks and carp that you could imagine. Digger was quite taken with them.
Quite a few motorhomes came and went during the afternoon but only a caravan remained for night time company - and that was gone by the morning.... So we pretty well had the place to ourselves.
