Hi, an unexpected visit to Houston mid July is on my families agenda. A road trip with an 8, 7, 5 yr old requires some planning . We would like to make reasonably good time on a scenic route with a good day or 1/2 day stop along the way that our family can enjoy with at least one night stay at each stop. Of course, this includes the way back from Houston to Chicago. Any advice would be greatly appreciated! Thanks!
