Yep, and Disney has to take some of the blame for this, having marketed themselves using images of Fantasyland rides for so many decades that, to much of the public, "Disney World" is thought to be a family amusement park with a castle.
That's the marketing which always worked in the short term, but at the expense of long-term perceptions of what makes Disney significant and special.
Honestly, if you tell the average person that Disney is about the unique experience of being believably transported to other times and places, a substantial percentage will say "I never thought of it that way."
