In the last 2 1/2 weeks I've stayed at the Marriott in Raleigh, the Oyster Point Marriott, SFO, the Marriott Singapore, the JW Marriott Kuala Lumpur, the JW Marriott - Union Square SF, and the Atlanta Airport Marriott. The KL property probably offered the best service, followed by the one in Singapore, then the JW at Union Square, SF. But then again, my only interactions were checking in, sometimes having breakfast, sometimes fighting with the lounge attendants over bottles of water (US, not Asia) and trying to chat up the rather fabulous looking front desk manageress (Singapore).
