We're staying at the Comfort Inn - Gaslamp (http://www.comfortinngaslamp.com/) a few blocks from the Convention Center We used. hotelplanner.com (http://www.hotelplanner.com/Hotels/2282-in-San-Diego-CA.html) to find it — they've got a good map showing the locations of all the hotels and the rate we got through them was better than through the hotel directly.
