We used to spend a lot of time at the different mall play areas. They are free and air conditioned!!! My little ones always had fun and the floors are soft in case of falls. Our favorites are Galleria, Valley View, and Willow Bend. Collin Creek is good, but it is a little small and can get pretty crowded. Stonebridge was just remodeled and we haven't been yet, but I am sure it will be nice.
