Many hotels don't wash the comforters on the beds in between guests. The comforters are big and bulky and difficult to wash, so hotels just leave them on the beds until they become visibly dirty. Certain hotel chains claim to change out all of the bedding in between guests- I think Hilton is one of them. So... does this bother you? Obviously there are many unsanitary things about hotels (glasses, door knobs, TV remotes, phones, etc), but the comforter is the biggest yuck-factor for me. I won't use the comforters if I'm unsure of their cleanliness status. It grosses me out to lay under something that other people have slept in (or slept together on) :yikes: Poll to follow!
