In Honolulu the ship docks at 1 Aloha Tower Drive & Fort Street. The main street close by is Ala Mona Blvd. Everyone knows where it is & you can't possibly get lost. I believe it's called Aloha Towers area. I don't know the Pier number. I did a search on my gps unit for health services near the pier & came up with quite a few places all within less than a mile away. A search for Honolulu marriage licenses came up with 1250 Punchbowl St. Honolulu, Hawaii 96813 Phone (808) 586-4400.
