I've had good experiences of this nature at the Sydney Marriott on several occasions. After enduring the 15 hour flight from either LA or San Francisco, all I basically wanted was a shower and a bed. The flights from the US typically arrive in Sydney in the morning, before most rooms are either vacated or cleaned at the hotel. On every occasion that I've stayed there, the MOD has offered to let me use the shower in the rooftop health club to freshen up and then have breakfast in the concierge lounge. By the time I accomplished these two tasks, my room was typically ready. It sure is a nice gesture after a long flight. I'm not sure if it is routine or standard operating procedure, but I've had no exceptions to the process yet.
