Just a few minutes from the bustle of Waikiki is an oasis of peace called The Kahala Hotel & Resort. Around 3AM the world fills with the song of hundreds or thousands of birds. Later in the day, guests can play in the lagoon with half a dozen friendly porpoises.
It's a different experience from countryside but definitely one of the most pleasant urban resorts I've encountered. We've been staying here for most of our adult lives.
