Not a campsite, but a note for anyone going to Disneyland with kids ... they allow motorhomes to stay at 20 euros per night, including a days parc parking which is 15 euros anyway.
You cant erect tents or awnings but if you can be self contained then its great and handy. There is a toilet and shower block also, provided for coach drivers I think but used by everyone. In the morning you get on the travelator to the parc entrance, or as we did the one day, on the train into Paris on the RER.
Might be useful to some?
