Staying at the dreaded Waikoloa Hilton Village. Not on our dime and sure it will suit us just fine. Trip is in a few weeks and we'll be renting a car to explore one day. Looking at a quick trip to 49 black sand beach and then spending a few hours at Hapuna Beach. Is there anything else in that quadrant we should not miss? Family loves beaches, quaint towns, and good lunch spots. Hate hiking and history. Not me. I love both. But my wife and step daughter are allergic to both those. Fwiw I'm a mosquito magnet so I'd like to avoid those. I'll only have the car for day time hours.
For reference they really enjoyed when we stayed in Oahu and took a day trip through the middle of the island and particularly enjoyed visiting Haleiwa, kualoa beach, and Kailua Beach.
