Unfortunately, due to problems with the shuttle boats to the Arizona, we were not given tickets to the memorial and had to wait in the standby line. However, the tour company did everything to accommodate us, including informing us of the situation the day before and offering a full refund. We chose to wait and although the line was long, we took turns visiting some of the other things at the site.
Pearl Harbor itself is full of wonderful exhibits and the Arizona is quite moving. They do a good job of impressing upon guests the solemn nature of the site.
Our guide, RJ, deserves a shout out. We missed our return bus (due to shuttle delays) and he called us and we were able to get a later bus easily. RJ was funny and informed and told interesting stories throughout the trip.
Highly recommend this experience!
