Family hotel/b and b in Paris or outskirts

[Naturenurture]

Hi there
Would appreciate any hidden gems either in Paris or easy to get into Paris for 2 day trips in. Will be with 12 and 9 year olds.
Many thanks!

We stayed at this B&B (B&B Brigitte) with 2 DCs (5 and 9) and 2 adults. Brigitte is very friendly.
Very central and easy to walk to quite a few tourists areas.

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.
