I have been upgraded to club rooms at the Eau Claire a number of times, and when I haven't I have always been given club access. Just this past weekend I was upgraded to a 2 bedroom club level suite. As a note, I beleive that the GM's name is Randy Zupanski.
In comparison, I have never received a decent upgrade at the Westin, despite numerous discussions with front desk staff. Instead of always trying to fight with them for an upgrade or even club access, I simply moved my business to the Eau Claire, which imho is simply a better hotel.
