We are just back!
We looked at the hotels but frankly they looked awful/overpriced and we didn't fancy sharing one room with 2 toddlers. We booked the centre parcs that is affiliated with Disney. They have certain apartments there which are allocated to Disney guests. That way we had a bedroom for us, one for the kids and a living kitchen dining room. It was beautiful, and has all the benefits of centre parcs - restaurants, shops, cafes, activities, a little farm, playparks and an incredible swimming pool.
If you book through Disney it comes as a package and includes your park tickets and free parking at Disney (usually 30euros) Centre parcs is right next to Davy Crockett ranch, literally next door. You do need a hire car obviously (if you are flying) but we preferred that anyway. It is a long walk from the car park to the park entrance but we had a double buggy anyway.
I honestly couldn't recommend it enough, it worked so well for us. We did the parks in the morning (you get magic hours) and went back to the apartment for naps, snacks, swimming, dinner (aka baguettes and cheese) little ones to bed, wine.
One thing I would say is that Disneyland Paris is smaller, busier and more dated than the Orlando parks so adjust your expectations accordingly and you'll be fine. In typical European fashion it's all a bit laid back in terms of lack of signs, bit disorganised, queuing is non-existent, but honestly we had a blast.
Hope you have a fantastic time.
