Yes, I have stayed there and it was fabulous! You can take the Eurostar there and the hotel will pick you up and take you to this wonderful property. Likewise, just South of you is the great Loire Valley, if you can make it there you will have some extra fun. Enjoy, you will be in for a treat! You can easily take the RER into Paris in under an hour and enjoy a great meal. I would recommend going to the area just North of the Arch de Triophe, and walking or cabbing to either the Relias du Venice (Steak only), or The Alsatian, across the street from the Marriott on the CE. You can't go wrong!
Perfect for famlies like you, if your first intention is to visit EuroDisney. The Villages are like a small 'home-town', 2 rooms, dinning area and kitchenet, all facilities (except restaurant), small bar only, mini market. But if you want to visit Paris downtown, is not the best option, taxi fares around 90 EU, one way.
