I'm going off the French
Hot on the heels of Sanef not letting me use a credit card for Libre-t, Camping-Car Park have just told me they are stopping the Liberté option. This worked the same as Libre-t, you just used the aires as you wished and they simply took the payment afterwards, simple! Now I've got to give them an amount in advance, they suggest €80!!!!.
My question is does anyone know if you need credit on your Pass'étapes to ENTER an aire? If possible then I can just add the amount to cover my stay when I leave. I've really got a thing about paying in advance for services I haven't yet used.
