From the Just Tickets website:
Note* - Tickets for all camping (lay-by) areas are now available from Wednesday to Monday only. The Le Mans authorities impose a daily surcharge for vehicles staying on Monday and Tuesday, payable in Euros on arrival.All sites are officially designated as lay-bys (showers are no longer provided). La Houx has numbered places, showers and electric points.
Is this right, are we gonna get mugged for our custom designed power shower?
