This is exactly why I pack my own comforter and just shove the one there under the bed or just call down for extra sheets. By the way, it's not that they hardly ever wash them, they don't wash them unless they get stained. Even then they sometimes let it slide. My friends mother worked for Holiday Inn and let me in on that little tid bit. The only items that they are required to wash by law are the sheets and pillow casings.
What's she doin'? Chillin' at the Holidae In.... That quilt story is NASTY! I'll never stay in a motel again.
