The concept to turn Splash Mountain into a Tiana ride was clearly developed for Disneyland, and cramming into Magic Kingdom's Splash Mountain is a huge missed opportunity
What they really should be doing is building a New Orleans Square at Magic Kingdom, maybe north of The Haunted Mansion, on that piece of land that's been vacant for 50 years? But have the Tiana Boat Ride and Restaurant there in place of DL's Pirates and Blue Lagoon
The whole appeal of Splash Mountain is "singing animals in a cartoon world" they should change that as little as possible...
Get Br'er Rabbit out of there already, maybe replace it with the unmade film that inspired America Sings.
These rides don't need to tell you a story to be popular, The Jungle Cruise, Small World, Haunted Mansion, Pirates "Pre-Johnny Depp" had no stories, they just had fun characters and fun songs in beautiful environments
