thanks all!
I like the idea of leaving the big bags at the airport for pick up and taking a small bag. Might be tempted to use the AREX then on the way from hotel to airport.
KE Limo bus is an option as well.
I'm leaning towards (we have plenty of time to decide) the Westin as I can use (hopefully) my free night cert with Marriott.
