Wife and I are in our 70's and have great flexibility in timing our visit. Will rent a car, and visit friends, stay at B&B type places, see Haleakala, sit on beach, etc. , then go to Oahu and big island. Prefer to avoid crowds to some extent.
Will probably go sometime between 1st of January to end of March for about five or six days. We need advice on the best time, and any other good advice.
