I live in the Mandarin Oriental Hotel here in Hong Kong but travel extensively. If I am gone for more than a night, I simply go to the front desk and let them know I am leaving. The staff hangs all my clothes in the laundry and packs up and stores everything in my room. They don't charge while I am gone. Now that is service!
