CQ, enjoy your vacation.
San Antonio is nice. There is a lot to do and see. We plan to hit Sea World, Six Flags, and a big water park about 30-35 miles away. My niece and her hubs like the water parks so we may try to get a two or three day pass for that. All that in addition to all of the stuff to see and do in downtown. There is a Mexican place there that I've got to find again...best Mexican food I've ever had.
