Overnight stop at Caen (Moved)

milliehull

 We are sailing from Portsmouth to Caen at the end of May arriving at Caen on the Brittany Ferries boat that gets in at 21.30.  We are considering staying overnight at the Municipal Site - Les Pommiers for an overnight stop.  Has anyone stayed there
and if so what can you tell us about it?  Do you know whether it will be open at that time of night?  I would appreciate some advice. Many thanks.
