We got reservations on-line early for a small cost. Our tour started at 9:15 and you have to be there one hour early or they will give away your tickets. Parking is crowded so get there early. There is much to see on the site before you start your tour including two interesting museums.
The tour includes a video and a boat ride to the Arizona memorial. It was fascinating
and sad at the same time. The ranger who gave the tour was so informative. This is a place everyone who visits Hawaii should see.
