Not everything yellow is gold. In many places they reaarange the towels after the customer goes to look fresh. You will be lucky if they showered after the previous customer. They are lazy and want to cut costs.The ones I have seen in hotels have used clean towels on top of the bed. Not one on the sheets in 3 years. Every one has been clean and fresh down there, but I guess you get that for 450 -500 an hour
