I will be in San Antonio for at least 3 nights in May for work (with gf in-tow) and would like some opinions on the best bet for PC hotels downtown near the Riverwalk. Best options seem to be Either of the Indigos, HI-Riverwalk, or CP-Riverwalk. Any upgrade success with Plat status? I don't want to venture out of this area because my conference is at the Hilton. The rooms there are too expensive and seem to be rather lackluster.
