Nothing is off the table.
If you had told me 10 years ago they would reroute the Disneyland Railroad, reconfigure the Rivers of America, and move the Circle D Ranch to Corona and make the horses commute on the Riverside Freeway every day to keep the Streetcars operating on Main Street, I would have laughed hysterically and assumed you were living in your mom's basement and dreaming of impossibilities.
And yet, here we are, all of that and much more was done to open a 14 acre and Double E Ticket expansion of Disneyland that's costing at least $1 Billion. 10 years ago no one (who was sober) could have dreamed up such a thing.
And now permits are piling up that clearly show they are going to bulldoze the entertainment warehouse just north of Toontown for more park expansion and another new ride. That's a warehouse that some folks here insisted could never be moved, never replaced, and never touched. But there it goes... buh-bye.
Moving a cubicle farm like TDA off property, sometime late in the 2020's or 2030's, is entirely possible in the 21st century when "Anything is possible at Disneyland! -Walt Disney"
