Paris, You will have a good time, if you have children. Euro Disney would be fun and very bi-lingual.
I think the musem the Louvre is a must, the champ elyesses, and the eifer tower of course,
Most cathedrals are beautiful and open to the public be sure to enter quietly, walk around and just enjoy the buildings...WOW
choose the Isle de la Cité, cathedral , quartier latin , banks of the river;
Enjoy the market and take in some fresh pastry. Yum, Yum,
Plan a day outside paris and go to Normady or to see a chateau. France is not only Paris and a true understanding and appreciation of France will come after you leave the city and see the country side and Castles.
You can take the train cheaply until the smaller towns and villages, Search on the internet for bed and breakfast in North of france, most are located in small villages and have english websites.
Plan a little escape from Paris, at a bed and breakfast and most are bi-lingual and take a winery tour.
This should complete your vacation and make it more enjoyable than just Paris, You never want to leave the country with just the understanding of a city but the understandingn of france, Then you can say that I lived there for a month and experienced france.
Enjoy your vacation. bon voyage..
