I've mentioned this before, but most hotels these days have a sign on the bathroom door saying something about their desire to save water and detergent, thus asking you to hang up your towel if you plan to use it again.  The thing is, I don't think I've ever stayed in a hotel that followed its own advice.  Hotels always replace all the towels in and around the bathroom, whether they're used or not.  Good idea; bad implementation. #travel
