We visited Pearl Harbor, USS Arizona and USS Missouri during a recent visit to Hawaii. We tried to obtain tickets online from USgovernment.org, but due to government cutbacks the hours have been shortened from 8-1 instead of 8-8, thereby reducing the number of free tickets. We were told that we probably could still obtain tickets if we showed up early enough, but didn't want to chance that. We ended up purchasing tour tickets(apparently tour operators can get tickets when the general public can't). The tour included pickup at our hotel, and guided tour to Pearl Harbor, USS Missouri, USS Arizona and the Punchbowl. I am glad we purchased the tickets since we went on our second day there and were not familiar with the highways even though it was easy to get there, we had a great tourguide who was able to point out things that we would have never noticed if we had driven ourselves. The two teenage boys on the tour with us were very impressed with the history that was made in Pearl Harbor and was something that should not be missed if you get a chance to go.
