Did that help?
The DAL-HOU would go through San Antone
The other part was useful I was sort of guessing that the bus needs to be part of a real rail journey. Will look to see how much it would be to buy a GLS-SAS (provided Amtrak is willing to sell that). Otherwise may have to bite the bullet and do a shuttle or look into renting a car.
