Re: Need suggestions when visiting San Antonio...
Right close to the Alamo is a restaurant at the top of the Tower of the Americas. There are five Spanish Missions in San Antonio. Go to Mi Tierra (not sure how to spell it), near downtown, and have puffy tacos...there is a Mexican market right close to the resturant. The river walk is the main draw, dress to be outside and stay in a hotel on the river if you can afford it. HTH 
I'm retired Air Force, good luck to your daughter!

I try to learn from my mistakes, and from yours when you give me a heads up :)
