Space Center Houston
Thsi place is so much fun. There are all kinds of wonderful things for you and your family to do. Like a lot of other people have mentioned it is expensive, but well worth it.
Toy Crossing
This storey has a lot of realloy nice things!! My son loves to see all the toys. Esp. trains!! It doesn't help that the area it is in is just beautiful. Kind of overprices, but lots of fun to take your kids for a special trip.
Houston Zoo
I don't think there is anything bad you could say about this place. The childrens part of the zoo is a lot of fun and the kids really love that. Esp. the petting zoo.
Putt-Putt Fun Ctr
This place has everything laser tag, batting cages, putt putt, bumper boats, and arcade. There is so much for a family to do. You could spend hours there just having so much fun!!
