The trip to Pearl Harbor is unforgettable. Only downsize was the Arizona was not opened due to repairs. Overall the day was exciting and well planned. If you are doing the Pearl Harbor book a tour makes the day less stressful and you get the benefit of enjoying everything without getting loss. Money well spent.
We very much enjoyed the visit at Pearl Harbor, the aeronautics museum and the tour/visit at the USS Missouri. The rest of it we would have been very happy to skip a bus drive-by through downtown Honolulu and military cemetery. Our driver, while perfectly pleasant, had done this trip one too many times and much of his commentary sounded rote. And I recommend skipping the prepaid VIP meal at the aeronautics museum.
One other thing we hadn't anticipated -- due to windy conditions, we weren't able to see the Pearl Harbor memorial close-up. No one's fault, but worth noting if you're making your plans last minute and have a sense of the weather conditions.
