I always check out our picture after riding Splash and sometimes the expressions are just priceless! But I never buy the photo because it always has other people in it that I don't know. I don't want to pay $$ for a photo including strangers.
So, I think it would be great if Disney would offer photos where you point out which of the people in the shot you want and the rest are replaced by images of Disney characters. How awesome would it be to look like you were riding with Mickey, Donald or Chip and Dale?
With standard photo manipulation programs this really should not be outside of their capabilities. And I bet they'd sell a lot more photos!
