The Canada Place in Vancouver where I boarded the Disney cruise has an attraction called the Flyover Canada. I did not go, but I assume it is similar to DCA's Soarin'.
Non-fiction attractions have a place, but I am convinced that Disney doesn't do a good job of it. The natural environment of San Francisco creates many opportunities to create non-fiction attractions due to location. Disney parks are located in vacated land and doesn't take advantage of local points of interest. Anaheim is located in former orange groves. Orlando was a swamp.
Perhaps Aulani is the exception where everything in Hawaii is absolutely beautiful, but it's not anywhere close to where people want to be like the Waikiki or the North Shore. The beach is really a lagoon. Close enough I suppose.
Hopefully this addition will be both tasteful and entertaining - my experience with Knotts' Mystery Lodge is that it seemed like an attraction that would be more at home in a museum than a theme park. Dreamworld has been moderately successful at attracting Asian tourists to the wildlife section of the park, it will be interesting to see how well "Corroboree" appeals to this market.
