Itinerary Rough Draft for Paris - I would appreciate your input! :)

Hi,
You have listed about everything there is to do in Paris, for your 5 days there. It's good that you have ideas but of course you will not be able to do it all. Here are just a few suggestions/comments.
Day 1. If you have booked the Versailles king's apartment tour, (must reserve) you don't need the Versailles passport. The tour ticket will give you access to all of the chateau, grounds, etc. the museum pass is for consecutive days, so since you are going to euro Disney on Friday, you should get a 2 or 3 day pass (Sat, Sun, maybe Mon?) I've seen the Paris Story, not sure I'd recommend doing it if time is tight.
I think an open bus tour is good for the first day, if weather is good and you can sit on upper deck. You did not say when you are going to Paris.
Walk along the Seine & Tulleries is good. (beach is there for limited time) Arch de Triomphe not close, save for another day.
Since you are going to Disneyland on Friday, I would take it easy on Thursday.
Saturday: if you take the bike tour in the morning, don't do St. Ouen in afternoon. Flea markets are morning events.

I prefer the Vanves flea market. Based on your bike tour of the city, you should have ideas for places you want to re-visit later in the day?
Do an evening river cruise any night that's convenient. Perhaps do Montmartre.
There is no admission to the Notre Dame cathedral, but if you want to climb to the roof, I believe the museum pass covers it.
Sunday: The Berthillon ice cream parlor may be closed on Sunday, but there are usually take away stands on the same street selling this ice cream. Where are you planning to eat lunch on the Eiffel Tower? I recommend walking a little way to the rue st. Dominique and going to Cafe Constant, Les Cocottes, or Fountaine du Mars. The first 2 are popular and very small, but you have a decent shot at getting a table for late lunch.(can make reservations too) Fountaine is a bit more pricey, but very quaint & highly regarded. There are several more restos in this area. (I recommend checking TripAdvisor for restaurant info for all the area you will be in in Paris)
See Arch de Triomphe and walk down the Champs Elysee a block or 2. Don't waste precious time walking all the way to Concorde.
You may want to hit Laudree a couple blocks down, it is usually very crowded though (in peak tourist season). There is another branch but too difficult for you to try to get to. You can go into the shop and buy macarons and pastries though!
Monday: shopping at any of the department stores you mention is good, as well as the souvenir shops on rue du Rivoli, near the Louvre. The Marais is a wonderful area for strolling, shopping too. If you shop at these stores, the Luxembourg Garden is across town and not that convenient to get to.
Of the other places you list as possible things to do, here are my suggestions ranked by my own personal preference, and your hotel location and time.
Musee Picasso
Centre Pompidou
Invalids
Luxemborg Gardens
Pantheon (is undergoing restoration and dome may be surrounded by scaffolding) The stairway in Midnight in Paris is part of a church right next door.
Cluny
Opera House (tour inside)
Probably not doable:
Catacombs - recently heard the line to get in runs 3 hours -- in summer now. I would skip this in any case.
Pere Lachaise will take a lot of time and energy too.
I hope this helps and is not too confusing -- you listed so much! Since you have been there you may have a good idea of what's doable, but perhaps things have changed. Whatever you get to see and do, I'm sure it will be great.

Also, The Rick Steves Paris guidebook (which I hope you have) lists optimal sites to see for 1, 2, 3, 4 days, etc. I would take his recommendations -- over my, or any other suggestions --- you will not go wrong.

I am having trouble reconciling this ...
An all day adventure in Disneyland Paris – gotta be honest – we are pretty excited! And yes, I know it will be different.

with this ...
Other things we would like to do but don’t know how to fit it in. (Am I missing anything??)
Invalides / Cluny / Pere Lachaise / Montmartre / Opera House / Pantheon / Centre Pompidou / Musee Picasso / Catacombs

Why leave so much potentially 'undone' whilst you include a visit to Disneyland?
I know the Magic Kingdom is for children of all ages, but in all reality it's a confected world of American artifice.
Excuse me for being so abrupt. Of course, in the end you must do what you want to do.
Lots to like elsewhere in your plans - have fun.

Oh, and definitely buy a 6 day Paris Museum Pass for use Thursday to Tuesday - at 69 euro it works out at US$12.60 /day.

BG gave good advice... My only 2 cents (sorry Betty!) is do not miss the Luxembourg Gardens (1-2 hrs)... my favorite place in Paris. It's a Must See in my book.

Paris Disneyland is fantastic! Plan to spend the whole day and be ready to stay late into the evening to see the fireworks show. It made for a late night but was worth it.

Hi Kelsea, I second BG's suggestion to take a look at Rick's itinerary for a few days in Paris. You've listed just about everything there is to do in Paris so you'll need to prioritize. Get a map and group your activities so you don't waste time back-tracking.

Get a Paris Museum Pass. It's great because you can pop in for an hour or two, get a cup of coffee, or use the restroom at any of the 60+ covered museums. Note that Versailles is also included in the Museum Pass.

Even if you sleep on the plane, you will be tired the day you arrive, so take it easy and explore the neighborhood around your hotel. Get your metro tickets and Museum Pass. Visit some of the smaller museums (Rodin?) and walk through the gardens. A short bus tour might be a good idea to get an overview of the city, but don't fall asleep on the bus!

I've been to Paris eight times and haven't done Disney yet, but that's your choice. If you do both Disney and Versailles, you're down to about two days in Paris. Have a great time and plan to return!

Thank You So Much To All Who Have Replied!

BG, thank you for the indepth advice.

We will be in Paris on July 23rd, 2015.

Does it matter what day we go to Notre Dame? Thursday or Sunday? I'm thinking Thursday would be better.

I need to look at a map and group these better - then I'm sure I can see more :)

BTW, I tried talking dd out of Disneyland Paris and that is actually her number 1 must do so we will make it a great time!

Thanks again!
