Don't do it by arrondisement. Go to the places you WANT to see. It is pretty unfulfilling to travel "around".
Get a guide book--I recommend the DK Eyewitness Guide to Paris because you can see things in one area and decide.

Boy am I in a contrary state of mind today! I apologize if I sound like Grumpy Granny with my suggestion:

I think you may actually miss Paris if you are so determined to fit in so much sightseeing in four days. Anyone who has told you to limit yourself has given you good advice.

Pick four things you REALLY want to see in four days (and no, not Versailles). Then pair four "maybe" things that would be in the same general locale. And then pair four "maybe maybe" things, also in the same locale.

You won't run yourself ragged that way, and you can take everything in better. Remind yourself that you can't earn a Girl Scout Merit Badge for how many things you saw in one day.

It's so funny that after this last trip, we just happened to watch Anthony Bourdain's "No Reservations" segment on Paris. And how he advised people to see Paris is EXACTLY what a lot of us have been telling our friends for years:

Walk, Plop (in cafes) and Eat.

By the way, you COULD leave shopping for Sunday. My favorite place to shop is in the Marais, where the shops are open Sunday. And that ways you'd have a chance to see my favorite street musicians, Les Musiciens de Lviv:

who usually are there around 3 pm in the Place des Vosges.

No matter what, enjoy.

That Anthony Bourdain show was terrific.
Yes, his method is bizarro.

Totally agree with AZ. Paris is more than the sum of its parts. An excessively agressive agenda risks spending more time looking at maps and watches than actually enjoying the city. There is a "Paris for Idiots" guidebook which I found helpful (since I qualified for the title)

Okay, I hope I now made sense. If not, I dont know anymore I haven't been to Paris and I've never done an itinerary in my life. I've always been a "hitcher" when it comes to trips. I didn't know preparing an itinerary was this hard. I thought when I found our apartment we're all good >.<

And yeah, since its winter so probably the parks/gardens that I listed are not possible so let me know guys. Thanks!

I still think you are racing around Paris to pass by a lot of things.
Why not head for the central part of Paris,and then see "your" arrondisement as a sort of "fill in" as you return. It is an interesting and eclectic area, but .... You could just wander around it in the morning or evening and see as much.
The Canal St. Martin is something to see after you have been to Paris a jillion times and then, maybe. The Bastille is of course, no more. it's a big square and an opera house.
Are you going IN any of the museums?

Museums in Bastille? No. So okay, I'll cross-out the Bastille/Canal St. Martin area. So I'll just allot our 4th day with Shopping, seeing some plays, and eating. HOw bout that?

I am afraid that each of your "days" will take 2 or 3 to do properly. The Lovre alone is worth a whole day, but that's my preference and may not be yours. However, having a list of things you want to do is a good start. It sounds like this is your first time in Paris, so I would suggest you take one of the tourist orientation bus trips that drive around Paris and point out the sights.

If you think you want to see many things for a short time and move quickly, it can be done. Here's a good start, which may be old but is certainly a classic:

As Peabody has said, it is just all tooooo much. "Plays". What plays? You speak French?
My favored time for the Louvre is about 2 hours just to emphasize people's differences--but the Orsay--more. The Invalides--maybe a look at the tomb, but that's enough, UNLESS you are a military buff.
In 4 days you cannot see all of Paris--that is a given, which I think many will agree. You can see a couple of museums (do you like the modern art of teh Pompidou?). You can see a good many sights/sites. You can truly enjoy walking around the city, stopping for a drink and people watching. Have your lists, but don't try to regiment them into days, that they truly won't fit in.

Your new ideas make more sense but as the others have said -- way WAY <B>WAY</B> too much on most days. You will be running like a mad man and never catch your breath.

There is no way you will see all of Paris in the short time you have.

I don't normally suggest this, but in your situation it might make sense. L'open tour are hop on hop off buses that will take you around central Paris and past all the major sites. That will let you see at least the outsides of many places and you can get off to enter one or another site then get on another bus to continue the circuit.

You could do that your first day in Paris to get sort of an overview.

Then plan your other days to fit in the sites you really want to visit.

I would try to list each day in order of preference. That way when you run out of time, you will have seen the your major "must sees".

With the time you have, I would eliminate the Moulin Rouge, Invalides except for Napoleon's tomb, Institute de France, and everything after shopping on your final day. I would add a Seine River cruise, perhaps on your first evening.

Do I dare suggest Rick Steves Paris guide book....look at HIS "must sees"-walking routes-public bus rides/routes....use his book as a reference point....take his suggestions for what interests YOU....also look at Michelin Guide Paris....visualize your "sights" & routes using the DK guide book ( heavy )....take a guide book with you and get a pocket street map...and see what YOU
want to see. Agree with janisj....an good overview via BUS Tour......remember, it's YOUR trip !
