For the new 2020 attraction, was $7 million the quoted figure for the buildings (not including ride hardware)? If so, it seems quite a lot for just a simple station/transfer track building and perhaps a queue structure.
Could we be looking at a new aquarium to go along with the ride?
We know SeaWorld are still keen on adding aquariums, a brand new one (Turtle Reef) is opening this year in San Antonio and San Diego is doing a major overhaul to one of their existing ones.
