You know, compared with other places/products.
Like, I don't know where is it, I know there's one somewhere in Florida and other near Paris, but there's almost no references about it in movies and any media.
And I have no idea what's inside except for people who went and told me.
Oh okay, so you're saying "why is it famous even though there's not much publicity about it". At least when I was growing up (middle class early 2000s), lots of people talked about it as the ultimate vacation to surprise their kids with (viral videos about such surprises would be popular on the news), and famous contest winners were known to yell "I'm going to Disney World" after a victory. The Disney Channel was like 1/3 of kids' television at the time and it ran adverts for the place constantly, such as exclusive sneak peaks of future attractions. Idk if they still run such a campaign but I remember the place having a serious cultural presence
