There's a lot to do, if you're wanting to do the Houston things, there's the zoo, aquarium, children's museum, space center Houston, a couple of Arboretums. In Gaveston there's Moody Gardens & of course as someone mentioned, the new Schlitterbahn which is indoors. Too bad Astroworld is gone, you'd have that to do too. You can look online for the locations. Moody Gardens has 3 sections plus Imax.
