We are going to visit Maintenon, Rambouillet, Castle of St. Jean de Beauregard, Château de Breteuil, Vallee de Chevreuse, Courson Castle, Domaine de Courances, Fontainebleau, and Vaux le Vicomte. All South of Paris of course. What would be a good central spot for these to base ourselves with an easy train there from CDG and rental cars as well? Thank you!
Same question for north of Paris to visit Chantilly, Compiegne, Pierrefonds, Giverny, and Chateau de Bizy. Thanks again.
