I advise taking it with a grain of salt. You might say, 'talking in hyperbole' has become something of a national pastime these days.
The thing is...there aren't all that many places in the USA/world that are as old as MK, while still retaining much of the same charm, fun and wonder. Ever rarer are places that have combined old traditions with fresh excitement as successfully as WDW has since over the past 40+ years! So folks are constantly torn between the comfort of familiarity/nostalgia and craving new excitement/adventures/discovery.
Further, we're living in an era of dramatic upheaval and change. Worse, a great many things people used to enjoy - say in the 1970's- are now not only out of fashion but absolutely detested.
In the 1970's, Santa Claus often had a pipe in his mouth and a bottle of Coke in his hand. Now smoking=death and full sugar soda is rapidly falling out of favor. People are scared.
In the 1970's, "Nature" was something nearly infinite, and women wore fur coats.
