We're going to Paris for 2 weeks this summer, and were considering including the above 4 Castles in our itinerary.
I have a couple of questions:
(a) Which of these are absolute must-see's?
(b) For the castles you recommend as must-see's, would it be better to take a day-trip for each by train to see each of them? Or, would it be better to rent a car and spend a few nights at a hotel to see these castles? If you recommend a car-hotel trip, how many days, and which city do you recommend?
Thank you very much for your ideas, suggestions and recommendations.
