At the CAN China Hotel Marriott, head towards the Starbucks off the lobby. Somewhere back in that direction is a stairway and under that stairway is a little stand that does laundry. It's a drop off, pick up spot as they take it out of the hotel to actually do it. I heard this at least a year ago, and have never looked for it or tried it myself....so if you find it, please post back.
