My husband and I are planning to extend his convention in San Antonio to a weekend Fri-Sun. Husbands convention is at the Crowne Plaza Riverwalk. It looks pretty stark and would like to stay in something with a bit more charm and character. Looking for $125 or under 3-4 stars are fine. Want to be very close to the Riverwalk as we will not be renting a car? When searching Hotwire it lists these two Riverwalk areas. Which is best? Thanks!
