I’ve always thought AK had the best theming of any park, but I’ve never thought it was necessary the best park. Visiting with kids has opened my eyes to this issue more. As a family park, it’s decent. I too think Disney CAN add IP in the Dinoland corner. This is for a few reasons:
1: It’s tucked away so it won’t mess with the overall theme, but it will add something for kids to do. Sure, the park is for families as a whole and not just kids, but I think AK is severely lacking for anyone under 7-10.
2: As you stated, the theming requirement is too strict. There’s not enough that can go into the park with how strict it is theming wise. It doesn’t have “lands”, as much as the park is really one continuous land.
3: Even in its glory, Dinoland was ugly. I love Dinosaur, but everything else sucks.
I think Disney can add Moana where Dinoland is and continue the conservation and nature theme. After all, much of the film is about Moana handling “diseased” trees and rotating the fishing grounds to maintain enough fish in each of the fishing regions to produce a viable amount of offspring for the next season. Leave out the supernatural force and it sounds like a perfect fit for AK!
Zootopia would be fine in the back corner. It would be separated from the rest of the park and would not distract from the overall theme. If anyone despises of it, just don’t walk over there! Besides the Dinosaur ride they would likely just reskin as a police chase ride, everything in this land would be an extension of AK that wasn’t there before.
