I have them do a bag of laundry each day. It enables me to travel light. And it helps keep my room smelling fresh. However, I always plan that they can, and have, lost my laundry and returned to me someone else's laundry. It only happened once on 20 cruises. So, I don't risk it and travel too light. Also, my whites are always some other shade when returned. I have learned to expect and accept it as the best they can do. I go home with a suitcase full of clean laundry.
