The hotel where we are staying is very interesting! Single beds, low to the ground and a compact shower. I do think folks in the US could look at using one idea that this hotel employs: liquid toiletry dispensers! Not constantly giving out little bottles of shampoo, conditioner, lotion and such would save a lot of little plastic bottles showing up in our landfills (and oceans).
Also, to use electricity in the room you have to put your key card in a connection box, and then when you leave, you have to take your key out, so everything is automatically turned off! Genius!
So often it is the simple ideas that save the most energy and waste. What other green and energy friendly devices have you seen at hotels during your travels?
