We are going to stay in a Disney Hotel in Disney Land Paris in 2nd week of July for 3 days/2 nights with kids (girls) aged 2, 11 and 13. This is our first time and would like suggestions to prep and plan ahead to make maximum use of our time there and not to miss any key attraction. Our package includes half boarding. Looking for plans for each day (morning/noon/eve/night), which park to visit first (/most) etc. What can we miss (and not miss). We will be in Paris the night before our check-in date so we are open to arrive early (and send our luggage to hotel and head directly to a park for check-in later in the day) if that is recommended. On day 3, we will need to leave by 11am in order to catch our train to swiss.
The DLP forum on DIS boards is very helpful

I visited Euro Disney in 2002 when there was just one park. It was pretty small so we were able to go on every ride there was. I have no idea how big the newer park is. The children will have a great time.
The Mousesavers board has a DLP page. Most of it is about obtaining discount tickets and packages, but since you already have yours all set, scroll down to some tips about supermarkets and the like, as well as links at the bottom to other websites and blogs specifically about DLP: https://www.mousesavers.com/other-disney-vacations/discounts-at-disneyland-resort-paris/
The disboard site above has been our go to for trip planning for DLP.
I don't want to sound negative but suspect as recommended above you will get better advise on a Disney board than this one given the nature of the question.
I went with our daughter late in 2016 there were 2 parks, one a studio type park and the other the main park.
We had a great day, but part of what I loved so much about it was how easy it was to get there and back from downtown Paris on
the high speed train. It was not our destination more a reward day for our daughter in the midst of our vacation.
The light show and fireworks at closing time are great! In July since the sun sets so late those will be quite late for your 2 year old though.
While we did not go on every ride or do everything we possibly could have I felt the one full day there was perfect and would not have desired another day there nor an overnight there.
We booked the Cinderella lunch for our daughter which surprisingly had excellent food ; was very expensive and had to be reserved well in advance. if you want to do that I would call them ASAP to see if available.
Otherwise we saw one show, cannot recall now what it was, and did all the rides we wanted to.
Lines were so much shorter than in the typical US amusement park ; may have been the time of year though.
Not sure I would have liked the rides with longer waits!
We did Tower of Terror first which was a good call in terms of the line as that ride gets busy mid day that and Ratattuoie were the 2 most popular I believe.
Hotel Terror was also a bad call as it was too scary for our then 3 year old!!! bad parenting dad!
The last ride we did just before closing was Space Mountain and one of the other roller coasters there were hardly any lines at that time. Wife and I went separate on that as our daughter was too young for it.
Make sure to bring a stroller for your 2 year old ; sure you would anyway just mentioning it.
I enjoyed Paris far more but was a nice treat for our daughter and she really enjoyed it. The Cinderella lunch was definitely her favorite. We bought her a nice Belle dress at the gift shop before we went to lunch so she could be dressed up. The dresses they sell at least some of them like that Belle dress are far nicer quality than the ones they sell in the Disney Stores in the US but cost was not different. Most of the other stuff in the gift shops seems to be the same as you find in the US.
Did not see any of the resorts on the property ; the train station stop is literally at the front gates so incredibly convenient coming and going.
If you are there for the 14th ; I would be curious if they do anything special for the Holiday?
