Eh. I'd say that about 90% of the time, the towels that I attempt to reuse by hanging them up get replaced anyway. This definitely happened every single day on my last two cruises, but it also happened at the last few non-Disney hotels I've stayed in.Every Disney hotel room ... for that matter just about every hotel room I've been in in the last 10 years has a little sign that says words to the equivalent "In order to save the environment, we won't change your towels if you hang them back up." Everyone knows it has little to do with the environment and everything to do with the bottom line ... environment is just the excuse.
