if you come here in Oahu .. . go AROUND THE ISLAND. like literally circle the whole island in just a day ... and then on another day be sure to visit the ARIZONA MEMORIAL ... then head out to Ko Olina Lagoons .. then end the day with a Lu'au at Paradise Cove... THEN on another day ... Hike Diamond Head .. and spend the night at Waikiki ... The main thing is probably beaches .
