Sadly, you have to pay to book a tour with a tour group or hotel if you want to visit the Arizona Memorial. The 1,300 “free” tickets that are supposed to be released and available at recreation.gov at 3p.m. each day are already spoken for by these for profit tour groups. Also, the park authority will not allow ride shares so be prepared for a bit of a walk and an all day wait in a standby line, with no guarantee of getting a ticket, if you don’t book with a tour outfit. We had 3 days in Honolulu and thankfully figured out the game on Day 2. We booked with hotel concierge and got on tour Day 3. Site itself was very moving and well done.
