The island’s largest hotel aims to have one of the smallest carbon footprints. Its 602 luxurious rooms feature not only pillow-top beds and Toto toilets, but also eco-friendly elements such as recycled-yarn carpets and plush robes made from recycled plastic bottles. Grass-covered roofs and solar panels reduce emissions, a hydroponic garden grows produce for its dining outlets (such as the thatched-roof Tidepools restaurant), and used cooking oil becomes biodiesel fuel. But that’s just green icing on the cake of this sprawling, family-loving resort where the elaborate, multitiered fantasy pool and saltwater lagoon more than compensate for the rough waters of Keoneloa (Shipwrecks) Beach. The 45,000-square-foot indoor/outdoor Anara Spa and adjacent Poipu Bay Golf Course offer excellent adult diversions, as do the fire pits overlooking the pool by Dondero’s Italian restaurant. To feel even more virtuous about splurging on a stay, check out the hotel’s volunteer programs with the National Tropical Botanical Garden and Kauai Humane Society, among others.
