I'm trying to work up the courage to try Hotwire or Priceline for the first time. I need a hotel room 10/9 - 10/12 (checkout) within walking distance of the Convention Center. My first choice would be the Westin. How do I know what 4* hotels are near the Convention Center? It doesn't have to be a 4*, but I thought that might help me guarantee an easy walk. Thanks, dfnh
