I'm only guessing here Smokie but I think what they are getting at is that they won't allow Motor Homes to park in the normal "Parking" areas of Bleu, Rouge and Antares, but that they will have an allocated area where they have to pay extra to park.
I know that in the last few years several people with motor homes have just parked in the normal "Parking" areas instead of a Camp Site or Lay-By yet still sectioned off areas as though camping. I guess that's what they are trying to eliminate.
Camp Sites (Houx) and Lay-Bys (Maison Blanche etc) should be OK I think, especially when you look at the prices they are quoting.
However, I'm sure Gilles will be able to come up with a more comprehensive answer by speaking to the ACO locally.
