Handling so many visitors every day of the year, both Disney parks have excellent facilities to cope with demand, spread evenly throughout each land and in most cases, fully accessible.
Toilets, or — to use the American Disney term, restrooms — are usually signposted in French as "toilettes" with the actual male/female signs outside coming in a wonderful variety of designs — in Main Street, for example, the modern stick man is replaced with the elegant silhouette of a top-hatted gentlemen!
Both male and female "restrooms" usually have baby changing facilities, or you might instead prefer the calm of the dedicated Baby Care Centres at each park.
The maps below show all toilet locations at a glance. Look out for the "(accessible)" note to indicate locations where there are restrooms adapted to meet the needs of disabled guests.
Outside the parks, you can find toilets at these locations:
Simply ask: "Excusez-moi, où sont les toilettes les plus proche?"
Toilets sometimes aren't that easy to find around the city of Paris itself, and most public toilets often charge for the privilege.
If you're visiting galleries or stop off in cafés, be sure to always make the most of the facilities before you leave!
