National Geographic’s Unique Lodges of the World www.nationalgeographiclodges.com
They describe their collection as “a network of world-class accommodations where sustainability is the touchstone…. These are not simply hotels, they are the concepts of dreamers come to fruition: unique lodges that defy the imagination in their design and detail, founded on a deep desire to protect the cultures and precious ecosystems that surround them.” A marketing mouthful. I am tempted to de-construct the “concepts of dreamers come to fruition” or the “defy the imagination” lines, but the places are all so cool that I will give them a pass.
