The Norweigan Cruise Line Ship Port is located at Pier 2 - Pride of Aloha, Pride of America, Pride of Hawaii. It is just a short 5 mile (about 8 kilometers) drive from the Honolulu Airport and can take about 10 to 15 minutes, depending on traffic. Cab fare should be less than $20, not including tip. Make sure to check whether your driver accepts credit cards, as some cab drivers only take cash or require a minimum charge to accept credit card payments. There's no extra charge for helping you with your bags but a tip is recommended.
