Ohhhh ok I see. They are banking on there being enough people within a close enough radius to travel there. Maybe that's why they decided to build 3 parks that are relatively close together (Toyko,Shanghai, and Hong Kong)?
Having never been to any other parks but WDW and DLR personally
Disneyland Paris made the most sense to me..there is a strong enough liklihood of the locals visiting but also you are in a strategic position where you can get tons of outside visitors who can easily make the trek there and even some people from United States and Canada have made the trek out there.
