Do you know how big is Disneyland Paris? Before I was there a few times I looked at google maps for the route and I recognized a Hugh circle of street around that park. What does that mean? The borders of their future parks?
Oh this is story. (just an old story told by my uncle, impossible to know if it's true)
At the time, when the Disney company still hesitating between France and Spain to build his park, they immagine build a park in the shape of the mickey head.
When our country won the battle (for many reason, one of this reason is because the government has proposed to give, for free, a dedicated "Disney TVG station", the extension of a metro line directly from Paris, and a highway junction), then they start to build "the mickey head". (apparently, they abandoned this pharaonic project)
At first, we know they want to build a third park (similar to EPCOT) but it's now compromised (for financial reasons, but also technical)
This can explain the big circle maybe [rolleyes]
Anyway, to answer your question, the complex is more than
20km², but Walt Disney own "only" (still a huge part) 40% of the company between this "financial structure". (There is also the french gouvernment, a US bank, a Saudi Arabian businessman, and many other I dont know) And this is why, you can thing "non-disney" things, like a big supermarket with more than 100 differents stores (bottom of the circle) for exemple.
If the financial situation allows it, we could have a third park without any problem (they have all the necessary space) but the future investments will be for the land and attractions "StarWars", so it's not for now ...
