I think AK's numbers will go down in the next 2 years until the new area opens up unless they add some entertainment options like a drone show or something. When Indy/Encanto open it'll probably hit 11M-12M range. Won't know until 2028. See you in 4 years.
I wish I could share your optimistic appraisal of the situation. If GotG boosted Epcot's numbers by 2 million, a reskinned Dinosaur and an Encanto ride is going to double that number for AK? I don't see it.
