Wild Arctic needs to go next door about 20 years ago. That’s really their only shot at a dark ride for this area is to us that land as an expansion.
I think they have a few options depending on how creative they want to get.
I think option 1 seems like the obvious one. Remove the WA simulator and replace it with a dark ride.
Pros:
Would drastically expand Sesame area and plenty of space
Cons:
Expensive to fill in simulators (to my knowledge they're a pretty good depth underground) and little potential for a new ride attached to the animal exhibit of WA
Option 2 is kind of a stretch, but totally could work. If they fit in between Shamu Stadium and the new building, they wouldn't have to remove WA and could fit a decent size dark ride
Option 3 would require the removal of the carousel and a building, I think it currently houses either restrooms or a nurses office. Also not much space there, but could probably fit something if designed right. Doubt they would want to put it there though, why remove stuff if you dont have to?
