Yes, I agree with Balso on doing the lunch at the Eiffel Tower after a morning visit to the Louvre. Just not enough time and you may feel rushed at the Louvre. I'm not much of a foodie so I'd do the Louvre that Friday AM but you might prefer to do a fancy lunch. Up to you. YOu could certainly do an Eiffel Tower visit without the meal that afternoon. I'd go for mid-afternoon if you have early AM Louvre tickets.

It's also an easy walk from the hotel to the Church of Saint-Sulpice. If you are a fan of Dan Brown's fiction this church played a role in The Davinci Code. It's a neat church and has an interesting gnomon.

Do re-work things taking into consideration the closure days.
I enjoy Giverny but I'd probably only take one day trip out of Paris and you're already doing that with Versailles...unless one of you is realllly set on seeing the gardens and Monet's home. There are a number of places to eat right outside the entrance to his home and down the main street. IF you go, be sure to walk to the church where he and the family are buried. There is also a very poignant memorial just after you enter the church yard. It's the twisted and bent propeller from a Lancaster bomber that went down nearby on D-Day or a day or so after. The memorial is to the crew who were all lost in the effort to liberate France.
I am a napper on the first day. I do make myself go out and walk around until lunch. Your hotel is pretty close to the Luxembourg Gardens - less than 1/2 mile so I'd walk over there after you arrive at your hotel if it's a pretty day. You might consider having lunch at La Terrace de Madame which is a small cafe located IN the gardens near the Medici fountain and then walk back to the hotel. I usually have a shower and a nap in the afternoon and I may have mentioned this, I set an alarm for 1.5 hours and then make myself go back outside. I know there are people who feel strongly about "powering thru" but I just can't do that. I feel fuzzy-brained and vulnerable and since I usually travel alone I need to pay attention to that. The short nap does not affect my adjustment to local time.
BTW, I recommend you download the app, Citymapper to help you navigate in Paris. It works great for walking and using the Metro.
What a wonderful time you will have!
