Dear A. H,
The great thing about living in the DFW Metroplex is the wonderful proximity to so many fun things! Even though some of the locations I will mention are a bit pricy, they are all within driving distance and all offer lots of family activities. We take our grown children and grandchildren to all of these fairly often, so you may actually see us there! Here goes--
The Rough Creek Lodge, just outside of Glen Rose, Texas is a bit expensive, but worth every penny. The Lodge is located on 13,000 acres (I think. It might be 11,000, but it's a bunch!). Many of the activities are already included in the price, as is breakfast and dinner. Some of the activities included in the price are 2 pools (adult and family), small lazy river, fishing, hay rides, s'mores after dinner, ice cream by the kids pool, bungee trampoline, zip lines, game room, exercise room, etc. For an additional fee, horse back riding, 4 wheelers, hunting, spa, etc. are available. We've had four generations at the Rough Creek Lodge several times, and everyone had a great time!
A bit further away, but still within driving distance are 2 great Hyatts--the Hyatt Hill Country, just northwest of San Antonio, and the Hyatt Lost Pines in Bastrop, just outside of Austin. Both have huge lazy rivers, outdoor movies, golf courses, game rooms, kid's buffets, sand volleyball, huge pools, etc. The San Antonio location is just up the road from Fiesta Texas. Schitterbahn is a good stop along the way.
Of course, with all we have to do right here in the Metroplex, there's always the "vacation at home" idea. Whatever you do, the main thing is that you are together. Have fun and enjoy your children while they are at home. Cherish every minute!
