I suggest you spend one day away from Honolulu. Take a leisurely drive up the windward coast...maybe stop and see the Blowhole and take cheesy photos on the From Here to Eternity beach. Take a minute or two at Lanai Lookout and strain to see the neighboring islands (you will if the weather is clear), and perhaps gawk at gasping shore divers as they scramble back up the cliffs after their shore dive there. Have lunch at the Crouching Lion Inn at Kaaawa (experiences about the food and service are very mixed, but you don't go for the food or service - you goes for the view, which is spectacular). Once you get to the North Shore, ogle the waves/surfers at famous spots such as Pipeline and Waimea Bay. Do stop at Laniakea Beach, where (if you're very lucky) you'll see Green sea turtles hauling up onto the beach for a bask in the sun. Keep driving to Haleiwa for shave-ice, souveniers and a stroll around before heading home. Nice way to spend a day.
