To the first post you made after mine, 
UmbrellaFish, I just wanted to say when you mentioned 
Pocahontas as one replacement idea that probably wouldn't work because of unpopularity, I couldn't help thinking the idea of 
Pocahontas characters on Splash Mountain makes sense because the film begins with her jumping off the cliff into the water below or whatever. She sings about "the voices of the mountain," too. And of course one of the shots that stays with me most from that film is the end of "Just Around the Riverbend." Still, I think the real reason is that 
Pocahontas itself is seen as somewhat racist by a sizable crowd. I remember getting into a very unexpected argument with several people when I suggested the film be in
 Kingdom Hearts at some point on a 
KH forum a year or two ago. I mean, I don't think the film is 
that bad.  
 
 
But I still say 
The Princess and the Frog makes the most sense and I hope it's the one they replace the 
SotS characters with. It is the most fitting considering 
SotS glorified the enslavement of black people, so... Still, I don't think Pocahontas possibly being unpopular would really affect Splash Mountain's popularity. I don't think they'd re-name the ride even with the characters changed, would they?
