I think this is a good time to talk about IP. I guess I haven't finished all the big picture stuff yet.
Disney's IP is immensely valuable. But it has to be used properly. It cannot be shoehorned into places it doesn't fit. There are two ways IP is used in this resort. The difference is a little difficult to explain, but it is important. It depends on whether the IP is the theme or the IP supports the theme of the land. To me, the land is the main driver of theme. Everything in the land must be coherent for the land to feel real. The park just holds similarly themed lands, but the land is the most important. So this describes how IP is used to keep the theme of lands coherent.
In some lands, such as Fantasyland or all of Disney Adventure, the IP is the theme. The story is real. You really are in Arrendale or Pandora or any of the other lands. This is the type of land that is in style now, like Cars Land, WWoHP, SWL, and lands like that.
However, in other lands, like Tomorrowland, or all of Disney Earth, the IP supports the theme. So, for example, an African village in Disney Earth. The IP used, The Lion King, supports the theme. The land itself recognizes that the IP is not real, that it is just a story. The Lion King is not real, it is only a story that the theater in the African village is performing. This is what allows IP attractions to fit in non-IP based lands. I think this adds depth to the land and makes it seem more real.
But of course, the IP placement must fit in the land in which it is placed. This is why I am comfortable with adding Buzz Lightyear to Tomorrowland, but not Star Wars or Marvel. Even if it's not entirely logical to have Buzz, a character from a movie about toys, be the mascot of a future company of space rangers, it fits, at least in my head. But doing something like Seasons of the Force or a Marvel event in Tomorrowland, that to me doesn't fit. It isn't coherent, it doesn't make sense that all the different participants in a Galactic Expo would overlay their attractions to showcase a film that came out thousands of years ago, because of course, Tomorrowland does not treat other IP as real. They are just stories, and in the case of Tomorrowland, stories that came out a long, long time ago. Even with Buzz, he is the centuries-old mascot of the Space Rangers. He is not real, he is just a story.
Sorry I got a little conceptual, I hope I wrote that in a way that at least makes a little bit of sense.
