If no one knows about a detail, is really "extra special?"
I mean I happen to be one of the minority of people who did know there are no public bathrooms in liberty square, and why the ground is different there and what the patterns there are for. And that the flags across main street aren't official American flags so they don't have to be taken down. I've also read Project Future and know and am interested in the history of the Parks.
But my kids don't know or care about any of those things. Nor does my wife, my bro/sis in laws, nor their kids. Nor do my neighbors or the 3 people at work that brought their families to the park, and 3 of them are DVC members. For the kids when we first started going, they knew that WDW was where Mickey lives, and Ana and Elsa. Then as they got big enough it was where you could ride Haunted Mansion and Thunder Mountain.
Those little details are basically easter eggs for a small portion of the attendees. An inside joke if you will. But people don't go to the movie for the easter eggs, they go for the explosions and battle scenes (at least if we are looking at recent history.) That's who Disney is marketing to now. They are shooting not for theme park fans, but for everyone. Disney is basically now marketing to childhood and entertainment, its almost that generic of a demographic/theme. You go to Disney b/c that is what you watched and did growing up. That is what your kids are watching now. That is what you are seeing on TV, social media, ect.
