Hi,
I will be with my wife in Paris Sept 11-17th. I was there before but it's her first time. I was wondering whether it's worth staying last 2 nights in Senlis with a visit to Chantilly chateau from there. Or whether we should just stay in Paris for all nights and not bother. Senlis is chosen because it looks like a nice medieval town so different from Paris itself, cobbled streets look awesome, Chantilly is easily accessible and airport is close for leaving as well.
We are arriving on Sept 11th in the morning, expecting to be at our 1st Arr hotel by 11AM, so dropping off luggage and following:
Arrival Wednesday
Explore by foot nearby Royal Gardens
Come back to hotel - shower
Do the 2CV tour in the car - 2 hours
Dinner somewhere nice
Thursday
Walk to Notre Dame and Ile de Cite area
Tour for Saint Chapelle
Chill by Luxembourg Gardens
Explore Latin Querter for dinner
Friday
Eiffel tower in the morning,
Brunch/picnic from Rue Cler in front of Eiffel
Montmarte and Sacre Cour in the second part of the day - tour ?
Saturday
Explore city towards Le Marais
Late afternoon Versailles with royal serenade and night fountain show - if we can get tix
Sunday
First entry to Louvre for 1.5 hour tour
Tuileries, brunch outdoors if possible
Afternoon leave for Senlis - Uber
Explore streets of Senlis/dinner
Monday
Get to Chantilly chateau, have lunch
Come back to Senlis and wonder around again
Tuesday
Early car ride for CDG airport
The question is whether this is doable or not worth the trouble and staying longer in Paris would be better. Small, charming town of Senils with medieval vibe is what calls out to me, and Chantilly is just something to do being easily accessible from there.
