Well there is Sea World, the San Antonio aquarium, and the San Antonio Zoo that has some nice tanks with all kinds of sea life. so I guess to answer your question.. 1 dedicated aquarium, then a zoo and aquarium combo... And a theme park. Zoo would be my choice though.
Our experience in taking our grandchildren is that the zoo was wonderful. The San Antonio aquarium is small, very smelly and more for a group party.
