I minimize clutter by stuffing a pillow or two (or maybe a folded up bedspread) into a drawer by the bed, and putting a couple more pillows on the shelf in the closet.

I always wonder how quickly housekeeping finds those...

(That's in a room with one bed. If I get a room with two beds and don't need the second bed, the second bed becomes the storehouse for all the pillows/etc I don't want from the bed I am using.)
