If they replaced Dinoland with Zootopia or something else related to animals and/or nature, AK would be less than a half of day for guests within a few years or so. There’s an Expansion pad up north that is surrounded by existing theme areas like Africa and Planet Watch they could build while a Dinoland replacement could either be an Asia expansion with a couple of IP’s like suggested before or a continent that never have its own theme area at the park like South America or Australia.
