Battle of the blankets

Housekeeping was slightly confused when I called and asked for a blanket in my hotel room. It was explained to me that the duvet (note: a feather thin, non-feather duvet) was very warm, especially for a city that hits 25 degrees Celsius in winter. I wondered what he would think if I told him that I usually sleep with a husband + sheet + blanket + 2duvets + one duvet + 4blankets + one more duvet...
