We were at the Marriott and NCL moved our luggage from our room to the ship. The cost was $34 per person and I booked it at the NCL office inside the Marriott. However, I think it's listed in the NCL excursion information booklet. The pamphlet I have says:
6:15 am Ilikai
6:30 am Hilton Hawaiian
6:45 am Sheraton Princess Kaiulani
6:50 am Waikiki Prince Kuhio
7:00 am Waikiki Beach Marriott
Tour Ends: 12:30-1:00 pm
Available: Day of Sailing Only
Carry-on Bags are allowed and are stowed in the overhead compartments of the bus."
The tour goes to Pearl Harbor to view the Arizona Memorial and then takes you to Punchbowl National Cemetery. Next they take you to "Metropolitan Honolulu" for a narrated tour of several royal sites and the Hawaiian State House.
I hope this was helpful.
