Thanks everyone for all the great responses. I still have a little ways before I have to make a final decision. I'm rather leaning towards SPG or Hyatt. SPG, through Le Meridien does have some more "off the track" properties. I may end up being lazy and just sticking with Marriott.

WRT hotels in the area - If I were here for myself, I'd try places like Westfields. Since I'm here for work, I frankly want to stay at the place thats easiest to get to the office from, which basically means the airport or the suites. I do plan on trying Westfields at some point, just for a change.
