I live in SA and there are many nice places to choose from. I just booked the Courtyard by Marriott on the riverwalk for my dd's bachlorette party. the cost was 99.00. There are also a couple of new Marriott properties on the north side of SA (nice area, lots of restaurants, centrally located). The rates are anywhere from 76.00 - 115 a night. The Crown Plaza on the Riverwalk also had a $99 rate through Travelzoo.
I would love to know how the other poster got a 99 rate at the La Mansion. I didnt see that.
