With them being dead set on IP integration, feels like turning Dinoland into Oceania would make the most sense, if they want to keep the Nemo musical around.
My question is, not if they will, but could they add another land where Rafiki's is and north of Kali?
The Conservation Station facility itself appears to be pretty landlocked between a canal, stormwater infrastructure, a road, Kilimanjaro, and backstage areas. Sure some of that could be moved with enough money but it would not free up that much land on its own. All that other stuff would also need to find a home elsewhere.
The big swath of undeveloped property lies just to the south of it on the other side of the canal, east of the railroad tracks. It could easily fit two smaller lands like DinoLand are one big land with additional walk-thru animal exhibits. When I glance at Google Maps, seven access options jump out to me, some better than others. I'm sure those better familiar with the park's layout and operations would be able to comment further on these or identify other alternatives.
1. Via the Wild Express Station, essentially allowing access only by train which does not seem ideal for access to an entire land(s).
2. Via the path to Wildlife Express Station to Rafiki's Planet Watch north of Harambe Market. This would likely necessitate the closure of that attraction, demolition of the railroad, and a bridge over or tunnel under the service road.
3. Via the alternate bypass path in the forested area between Asia and Africa. This access point would also have to deal with the service road and railroad issue one way or another.
4. Via the area immediately west of or in the location of the bird encounter. You might be able to squeeze an access path in between the railroad and backstage area.
5. Via spurring off the eastern trail of Maharajah Jungle Trek.
6. Via the swath of empty land between Kali and Everest. It would be a long walk to actually get there, require some screening, and likely require the re-routing of E. Savannah Circle.
7. Via significant reconfiguration of Kilimanjaro Safari and Gorilla Falls. This one seems the least desirable and very unlikely.
