We used Camping 4 Vents. About 15 minutes drive away, easy to reach, and very well run by helpful people. Not cheap, but as good a site as we have been to abroad and if you want to go to Paris they will direct you to a station with a good service and free parking. We have been three times so it proves we were happy.
They can be booked through either of the clubs if that helps, but if not you can still get a lot of information on their web sites or go to http://www.caravaning-4vents.fr/campsite-france-seine-et-marne-paris-4-vents.html
