The catch: The Frontier flight has one stop and takes 5h 32m, United's nonstop takes 3h 31m but costs $669 per person, and all three hotels are in North San Antonio, not downtown.
Worth it if you want Tex-Mex, history and the River Walk for less; skip it if a connection or staying outside downtown bothers you.
