I am 100% fine with Rivers of America going away for Cars Land:
- Tom Sawyer Island and the Mark Twain Riverboat still exist in Disneyland
- There's no clear "how to improve these" plan with those two attractions
- Haunted Mansion's going to be the entrance to Villains Land anyway
- It allows Disney to drop the Liberty Square concept for something else
That means Hall of Presidents goes away too. And that's also okay. It's the lowest-rated attraction in Walt Disney World for many age groups. It's politically charged. There's no path forward for the attraction as it is.
That said, if they wanted to do The Muppets American History show, I would love that.
