I am not a tour bus fan and booked our own day trip from Maui with Adventuremaui.com with first flight in the am and rental car. I was told that everybody had to stay in line and chances for tickets are same for everyone. But a light should have come on when they suggested that I might want to make reservations on a website that is always booked out or not available. Don't get me wrong, the trip was great and the memorial is really touching and awesome even without the trip to the Arizona. But you are better of going with an organized tour from Maui, if you want to visit the USS Arizona memorial. The tours did not wait in line and had their tickets in advance. A park employee told me that the tours have this all booked up and make the reservations months in advance, for a memorial that is supposed to be free. We also talked to people who had just booked the day trip that week and they also got on the Arizona and all the other exhibitions, but they didn't leave Maui until 8.30 am. We had to get up at 4 am to get to our first flight to Honolulu. I would hate to see this happening to a veteran who really needs to visit this!
