Couple of tips for you:

Booked the travel part myself:
I flew from Edinburgh to Charles de Gaulle and took tgv train which was so much quicker than the Mickey Mouse airport transfer bus.
Booked the rest through DLP holidays:
There's an extra service that keep your luggage for you when you arrive at the train station, means when you arrive you can just go straight into the park - yay! Same for when you check out to go home, leave your bags safely at the train station.
We got a deal of free additional days eg pay for 3 nights get 4 nights.
Half board plus also gives you extra snack vouchers to be used through the park. Means you get a daily drink & donut/ice cream at some of the stalls. Could be a saviour when kids kick off!
We got extra park hours, we were ok to go into the park 2 hours before doors opened to the public.
Definitely book your restaurants before you go - this absolutely saved our holiday!!!
As other folk thought they could just turn up, queue and get a table for all their family - errr no! That's a nightmare especially as the themed restaurants are fab eg Remy's, and when your kids are hungry it's great to say ok lunch is booked at x place at 1pm, dinner booked at x place at 6pm.
Reserve by calling the dlp holiday helpline after I'd booked the holiday.
If you don't book in advance you may end up in the Fast food joint of chicken nuggets and fries, fighting for a table to all sit down.
There are shuttle buses to/from the hotels but ours (New York themed) was walking distance to the park doors.
Look at getting Fast Pass for getting on to the rides you want without queuing, again it's a god send!
Think you can get a Disney pram when ur there - best to ask about this when you call the dlp helpline.
Also ask if there are any other services available as there will no doubt be new things since we were there.
Download the free app that shows you a map of the park - you can see where all the rides and restaurants are. Also showing you the length of time of the queues for the rides.
Taking the time to do these planning tasks will be worth it - trust me, you will have the time of your lives!!!!
