Playa Viva, Zihuatanejo, Mexico

Off the grid and self-sustainable: It's the end of the world as you know it, and you feel fine because you and 21 others are kicking back in beachy paradise at this completely sustainable boutique hotel between Puerto Vallarta and Acapulco. It could be a real-world Survivor situation, but at least you'll have an organic garden, a biodiesel vehicle, a fuel-producing facility, and—so long as the sun still shines—100 percent off-grid solar power and thermal solar hot water. Did we mention that the force (field) will be with you? This was once a Maya and Aztec community and is now an archeological site.
