While I agree completely with this -- you have themed resorts and that is part of the appeal; why are you trying to eliminate it? -- I also think it's a bit silly that they're changing direction based on social media reaction (if that's actually what's happening).
Social media (or fan forums, for that matter) is not a good indicator of what the public, or even the overall fan base, thinks about anything. It's a small, self-selected sample and not at all representative of people who visit Disney World.
I'll certainly take it, though, since I don't want to see the rest of the Boardwalk turned into bland genericism.
