I'm planning a trip to Texas from May 15-19. I was originally planning on spending the entire trip in Austin, but in doing some research, it seems like San Antonio is a must-visit, as well. Do you think doing both is doable in my allotted time, and if so, do you think staying in Austin from the 15-17, hopping over to San Antonio from the 17-18 (would get in relatively early on the 17th), then going back to Austin for the final night would be worthwhile? Basically, I am flying in and out of Austin, so I do need to start/end there.
Also, recommendations for both cities are welcome! I chose Austin mostly for its bar scene and San Antonio because it just looks pretty and has a lot of cool history.
