That is exactly what Disney is doing now. They are making an effort to attract guests to it. That shows they care.
We clearly have a different definition of what "showing they care" means. What they're doing is much the same that they've been doing for the past twenty years or so-shoving in IP regardless of whether or not it fits. If they really wanted to "show they care" while maintaining the integrity of the attraction, they could, say, redo the show with more modern country songs. But modern Disney is apparently deathly afraid that if you aren't constantly being bombarded with IP at all times, you couldn't possibly enjoy the experience.
You nailed it on the head. The majority of guests want to be surrounded by Disney IP. They travel across the world to find the familiar characters and music they hear on Disney+ and in theaters and on TV. From the Guest Surveys, they want to experience what they are familiar with.
Then that's a sad indictment on the state of what people want. Most of the attractions that everyone's heard of, even that have never been to a Disney park, that Disney made their reputation on, aren't based on Disney IP-or at least, weren't at the time they were created. And those attractions still seem to have long lines too, so it's not as if people just can't accept things without IP anymore. If people really just want exposure to the same characters over and over again, a Disney+ subscription is a heck of a lot cheaper, and if they're not even going to really try to create an incredible experience with an IP, people might start to wonder if they should have just stayed home.
People loved Disney parks when IP wasn't the only thing they were doing, and it's disingenuous to pretend otherwise, or that people would reject original attractions if they were offered them. It's quite lazy, as both a guest and a corporation, to just want repeated, regurgitated exposure to the same content over and over again. And again, if that's what you want, it's cheaper to just stay home and watch Disney+. If I want to ride It's a Small World, there are only five places in the entire world I can do that. If I crave exposure to Monsters Inc, I could watch the movies and other spinoff media anywhere there's an internet connection for a HECK of a lot cheaper than shelling out money to go to a Disney park. And given how mediocre some of those MI experiences are, maybe it would have been better and cheaper to just stay on my couch.
Really, Alien Encounter and its multiple incarnations leading to Stitch. Tiki Room, to its new management, and back. California Adventure 2.0 anyone? Disney Studios Park even today? Have you looked at the Hong Kong Castle today versus 10 years ago? They sure do admit mistakes and then move forward from them.
Which is totally why they're regressing at DCA and destroying the legacy of many of the changes they made as we speak. Or they somehow didn't make the Tram Tour at the Studios Park in Paris any better, but just added Cars characters-something that is completely embarrassing. Or have kept playing the BATB Singalong that seemingly no one likes, even people who usually defend everything IP, instead of just restoring Impressions de France. You're right, they're great!
