Very well done and well organized! If you don't book your free ticket to the monument (at least 1 day prior to your visit, there are limited available), the lines can get pretty long - we didn't & our wait was 20mins. It seems like they alternated boat loads between ticket & non-ticket holders. The memorial is always very busy, if you're worried about COVID be sure to wear a mask.
In addition to the memorial there were videos and exhibitions that just were brilliant, we ended up spending 1/2 a day here. You really get an insight & on-the-ground view of the attack from an array of perspectives & a look into the consequences that followed. Some parts were quite harrowing, be prepared for a few tears.
BOOKING A TICKET - Every day at 7:00 am, a limited number of “next day” USS Arizona Memorial tickets are released, they can be booked on the government website for non-refundable $1.00 fee.
A NOTE ABOUT STORAGE - You cannot bring your bag with you - only a purse, water bottle and phone, there is a storage facility - all day small bag storage was $6USD, we didn't mind but just be aware.
BOOKING A TOUR? We did not as there were numerous exhibitions and a cinema viewing on a loop that was very comprehensive. Also all the guides & U.S. sailors are brilliantly knowledgeable & helpful. But this would be a personal choice.
