Walt was wrong when he said about the Florida project, "...there's enough land here to hold all of the ideas and plans we can possibly imagine." He was focused too much on making gobs of money with EPCOT rather than creativity.
Of course time has proven him wrong in that TWDC has theme parks all over the world, a cruise line, the DVC, Adventures by Disney and Disney Sports Enterprises. And of course I don't need to mention their film, TV and other entertainment interests.
TWDC became a powerhouse in spite of what Walt wanted. It was a blessing to the company and the shareholders that Walt passed on in 1966.
