We livr in Houston and are thinking about spending 2 nights in San Antonio, 2 nights in Austin, and 2 nights in Dallas. Our two families have 6 kids (4,4,8,9,15, 17). We have been to all three cities numerous times, but were thinking we could hit up unique off the beat and path attractions. We could also hit up restaurants featured on food network. Does anyone have any advice for this type of trip? Thanks!!!!
