Thanks for the tips. I'm mostly into freshwater, and a biotope exhibit would be nice. Marine tanks are cool, but I only like the reef/coral.
The New York Aquarium will probably do, maybe we'll have time for rides and food at Coney Island too.
Any other suggestions for what to do there (can be non-aquarium related) would be great. I'm going with 3 girls, so shopping is probably all they will want to do.
