Peace and quiet prevails at this spacious former plantation that avoids artificial, postcard-perfect grooming. Extra-tall coconut trees could be a century old. Pretty gardens surround the pastel-colored, wood cottages. A hen might usher her brood across the grand lawn and palm grove. The long, undeveloped beach was made for walking beside the blue Pacific. And snoozing on a cottage porch or in a lounge chair is inevitable.
