Pretty soon, we might not be able to refer to them by name at all.
It'll be like charades, only more generic.
If you look at some of the older things that came out in the 1970's and 1980's it says Disneyland/Disney World on it. I have a record of the park not sure what year it came out but it does have both parks listed. Also the same things with my 1979 lunch box of the parks with the wrong monorail shown for Disney world.
