St. Regis Bangkok
While staying at the St. Regis Bangkok about seven (7) months ago, we got four (4) pieces of laundry per person per day. This is with Platinum status and using SNAs to get upgraded to a suite in advance. But I believe that the benefit was tied to SPG status and not the room type.
The laundry benefit is amazing when traveling with children. Not having to load a suitcase with dirty clothes and bibs for the rest of the trip was much appreciated.
I believe that the Sheraton in Singapore offered two pieces when I was last there years ago (maybe 3+ years ago). It didn't help though as I didn't have a long enough stay to get my clothes back.
