I doubt that they would do a cold water wash for 1 person's load as many guests' laundry is washed at one time in a giant washing machine with whatever their standard water temperature is (warm? hot?). Same for drying- large dryer to handle multiple oassengers' loads at once. You could always use the launderette to wash/dry special items to your liking. I do this occasionally....dry half-way and then hang up in my suite to finish drying. Easy-peasy.
