Where to stay in Paris for easy access to DLP and centre?

[Goposie]

We will be staying for a couple of nights at DLP midweek but have the weekend before and four nights after free. As I will be driving over I am looking for a reasonably priced hotel or apt where I can park. I don’t fancy driving into central Paris and I presume parking at hotels there will be pricey. So happy to be somewhere between Paris and DLP which has easy access to metro or rer. Any suggestions appreciated.

La Croix de Vieux Pont is an excellent holiday park and has a coach which leaves the campsite direct for Paris quite early in the morning and then returns in the evening.
Camping Le Chene Gris is another nice park with very easy train access to central Paris. The station is a stone’s throw from the site and it takes 45 mins into central Paris.

Thank you!
