<p>How long to stay? How long have you got? If it were me, I’d spend several weeks which would include time for day trips, but you probably don’t have that kind of time. I agree that you should find out what the others want to see too.</p>
<p>My must sees in Paris:
Museums/Churches
Louvre
Musee D’Orsay
Carnavalet Museum (history of Paris)
Pompidou Center (I don’t love it and it hasn’t aged well, so maybe just gawk at the outside and take a ride on the escalators)
Notre Dame
Sainte Chapelle (my then six year old’s favorite)
Eiffel Tower
Other stuff
Walk through the Tuileries, along the Seine, in the Latin quarter
Watch the kids sail boats at the Jardin de Luxembourg
Look at the cool windows at the Arab Institute [L’Institut</a> du Monde Arabe - Jean Nouvel - Great Buildings Architecture](<a href=“http://www.greatbuildings.com/buildings/L_Institut_du_Monde_Arabe.html]L’Institut”>L'Institut du Monde Arabe - Jean Nouvel - Great Buildings Architecture)
Tour the Roman ruins under Notre Dame
