While in the Marais don't miss the "Carnavalat Museum", very small, will take you less than one hour, but well worth it.

The "Orangerie" is O.K. but not that great. With all your other museums, I'd skip it. Also, St. Chapelle is beautiful, but when we were there in Sept. the main windows were out for repair. You might want to check on that.

The "Louvre" is overwhelmingly huge. The "D'Orsay is really the best.

Your itinerary sounds ambitious, but great. We've been to Paris 5 times and I still have things on my list to see.

Carnavalet is not small. There are at least 2 floors and 3 wings to my recollection. We didn't finish it in an hour (actually, I think I missed some rooms). It is interesting, and free to enter.

l'Orangerie IS small and won't take more than an hour to see. If you go about an hour before the cashier closes, it will probably be almost empty.
