I'm back!! I just spent a lovely three days in the company of some very entertaining librarians. In the process, I spent two nights in a hotel, which I don't think I've done since...oh...1978. It was a Marriott and yes, they did allow you the option of leaving your towels on the floor/bed (read: replace with fluffy new clean ones) or hanging the towels back up (read: I am fine with using my damp not so fluffy towel again tomorrow). I did hang my towels back up and housekeeping did refold them...so at least I felt like they were fluffy, new and clean.
As is evidenced by the cute little hanger on my bathroom door, The Marriott does incorporate some of the ideas suggested by of Green Hotels for becoming a more environmentally conscious facility. And while I did not stay at this hotel, it is clear that Marriott is looking towards a greener future. No, I do not work for Marriott, and no, I am not getting any Marriott reward points in exchange for this post. :)
