We took a 7 day cruise through Norwegian Cruise Lines (NCL) and had a blast!
Flew into Maui, boarded the ship, and the fun never stopped.
NCL has three ships. We went on the Pride of Aloha. Would recommend one of the other two. Pride of Hawaii or Pride of America. Both are much larger. But the price was right and the fun was great.

Got to see plenty of Hawaii and left enought not seen to pack another full week.
