Hyatt Regency Bonaventure
Weston, Fla.

The Bonaventure was the first property in its county to earn certification from Florida's Green Lodging Program for its eco-friendly initiatives. Within a month of replacing the incandescent light bulbs with compact fluorescent bulbs in all 501 guest rooms and common areas, the resort's energy bill was cut by more than $30,000. The hotel uses Smart Cars to ferry guests around, and the kitchen staff recruited a local elementary school to plant an organic herb garden.
