Downtown Aquarium Houston
Part aquarium, part small amusement park, which is either a bonus or a hazard depending on your kids. The Adventure Exhibit runs through themed zones including a sunken temple, a Louisiana swamp with alligators, and a shark tunnel. White tigers live in a large indoor habitat that surprises everyone the first time. Outside there is a small train, a Ferris wheel and a carousel, plus a restaurant with a huge central tank. Rides are individually priced on top of aquarium admission so decide the budget before you walk in.
