Honolulu
The most visited historic site in the Pacific. The Arizona Memorial requires a boat (included). Go early — afternoon crowds are crushing. Bring tissues.
Reserve timed-entry tickets up to 90 days ahead at recreation.gov — free but extremely limited. Arrive 30 min before entry. USS Arizona Memorial boat included; USS Missouri tour is $32 extra. No bags allowed — not even small purses. A bag storage facility exists on-site but the line is long; leave bags in the car. The USS Arizona memorial is not in the ticket: reserve it online 56 days ahead, or the day before at 3 pm HST.
All weather; light rain creates a more appropriate, somber atmosphere.
