Start with the disneyland paris app.
Put it in list view and you csn see info on all the rides, shows etc in each park.
You can tgen put a heart on any you want to do, and it puts then in a wish list.
Take into account height of your daughter and what type of rides she will like ( some are daring, others arent).
I would probably aim for ones such as tea cups, dumbo, carousel, small world, storybook ride in fantasyland. ( i like Peter pan but it is often a long wait for the length of the ride).
Buzz lightyear in discoveryland
The train ride around the park from the station in main street - go all the way around back to main street.
In adventure world- flying carpets, carz quatre, slinkydog, maybe the other cars ride. Spiderman is fun but is 3d. I haven't been on ratatouille for a while, and it isn't 3d anymore. I haven't been on any of the new rides. The nemo ride is dark and spins quite fast - also has long waits so i would avoid.
Adventure world also has the new frozen land - i haven't bern since it last opened.
All the shows are suitable for all ages.
October will be Haloween season so there will be a seasonal parade and some seasonal meets- info on those will update in time.
I would semi plan - have an ideas of what you want to do, but not be too fixed in how you do things- you need flexibility because of wait times varying etc.
Most character meets you queue for, but some you have to reserve online. You have to be in the park to reserve ( scanned your tickets at the gate) and be quick on release.
The app shows if it is a character that needs to be booked - in think it includes the princess pavillion, superhero meet, meet mickey and not sure what else. You can try in between releases because sometimes odd slots appear if people cancel etc.
If you want to get an idea of rides etc maybe watch some vlogs or videos on you tube. I follow Fairygodmother, sam4god and see you in main street, but they may not have as many vlogs that show rides.
Have a great trip. I would love to go in Halloween season.
