I'd stay in a tent at Manini Beach. The location is, I think, the best in the world. Luckily, my family and I got to stay at Regina's lovely house. It's built for both Hawaii living, with a large, beautiful lanai overlooking Kealakekua Bay, and Airbnb, with a well-stocked kitchen and thoughtful touches like portable A/C units. The house is clean, easy to navigate, and a perfect size for any family of four to eight people. Mahalo Regina!
