I never use more than one, but would like to use a good quality one. If I´m only for a single night, I might even reuse the one my wife has used. I simply detest wasting resources like fresh water to wash towels that have been used only once. Many, many times I´ve tried to hang the towels on the rack and still they´ve given me new ones every day. What a waste, IMO.
As we can see, customers have very different preferences.
