Another grocery store serving
Disneyland Paris is the Champion store in the town on Bailly Romainvilliers. The hours are shorter that those of Auchan, but, unlike Auchan, the Champion store is open Sunday morning. Champion primarily serves local residents, not tourists, and the prices seemed reasonable. It's a full grocery. You can buy fresh milk, wine, frozen foods, fresh baked goods, seafood, and more. Near Champion, there's a florist, a bakery, a drug store, and several neighborhood restaurants.
Champion is not far from Davy Crockett Ranch. It's walking distance from Marriott's Village d'ile-de-France. And you can get there on the number 34 bus from the bus stop adjacent to the Disneyland Paris RER station (the schedule is posted at the bus stop).
