Some of our favorite green features at Kimpton Hotels: Cleaning Supplies: All rooms cleaned with environmentally friendly cleaning products. (This one might be our favorite.) In-room designer recycling bins: Guests are encouraged to participate in reducing environmental impact. (We tried to think of the last time we saw a recycling bin in one of our hotel rooms, and couldn't!) Water Conservation: Implementation and auditing of low flow systems for faucets, toilets, and showers. As a bonus, Kimpton has locations all over the country and really reasonable rates. We just reserved a room in Northern California (with a AAA discount) for $89 plus tax.
