Honfleur is one on its own and no way can you compare it with any other Aire.We were at Honfleur a few years ago it was 7 euros then, packed in like sardines and didn’t dare think what would happen if there was a fire. There was multiple connections to every ehu. The toilet emptying point was overflowing and running down the site. I would rather pay a few extra euros and go on an ACCI site.
But as you say , always full so some must like it.
