THe point is by using that article as a guide, it illustrated that the big classy aquariums bring ALOT of visitors. More visitors for the casinos too, businesses, etc.
And I am sorry, I have been to the World Aquarium in the City Museum twice. Might have been bad days, but I found it somewhat below par, even for its size. Dirty water conditions, fish looking distressed, etc.
St. Louis could benefit no doubt about it.
