You can plan a trip to san antonio or austin that is really cheap. You can take a train ride to either of those places well they also have other destination that you can take. They also have packages that include a sleeper on the train, dinner or you can just stay at a hotel of your choice with in the town you choose. I think the website is www.amtrek.com or http://www.amtrakvacations.com/. I always thought it would be something nice an different for a getaway that is inexpensive.
Well have fun!
