Hi, we are staying on the Big Island but are coming over to Oahu for one day to see Pearl Harbor. Our flight arrives at 6:56 am and we are renting a car. Our return flight is at 6:52 pm. I have already reserved Arizona Memorial tickets for 10:30. So we will go straight to Pearl Harbor and hopefully see maybe the Bowfin before the Arizona Memorial. My husband also wants to see the Missouri. But I am thinking that we will have time when we finish at Pearl Harbor to maybe see something else. I am looking for suggestions as to what to see?
