If you are staying on Oahu for a week or more, consider staying at the North Shore in Kahuku. This upstairs condo makes you wish you lived here and a grocery and gas and food trucks are just a few miles from your front door, making those unlimited miles worth the expense of a car rental after all. You will spend time on the road going where you want to be, but it will offer you great flexibility and a beautiful place to land every evening when you return from your day's adventure!
