"Toy Story already having a presence elsewhere"
That hasn't stopped Beauty and the Beast having appearances across three parks so far. And Beast is a sort-of animal so is a perfect fit for Animal Kingdom, to complete the full set.
But everyone is still scratching around trying to justify the inclusion of this-or-that IP, why it would or would not fit into a particular park, but it's all rubbish isn't it. As I've mentioned, it's all retro-fitting excuses. That's the problem with the IP mandate, trying to retro-fit an IP somewhere where it was not envisaged for. Fitting a square peg into a round hole. If the peg doesn't fit, hack the hole around. There, that's better, fits now. Don't know whether it's easier than actually inventing a an attraction that's custom built for a particular place with a story that hasn't been told before, you know, put back the imagination into Imagineering.
