Not neccessarily.
People want to go to Disney because its full of better rides, shows and foods than your ordinary amusement park. They go to Disney also bec ause of the Disney effects they cant get anyplace else. They want a Disney experience but they dont care how its thematically put together, wether things fit as we fans think they should, or what Walt envisioned. They get out of it enough to enjoy their vacation and their time at WDW isnt affewcted by minor details like does Lion King belong here or there.
