No, because it takes too long to sail to Hawaii from California. If they based the ship in Hawaii and just sailed the Hawaiian islands, yes. As it stands now, that is not possible. There is only one ship (an NCL ship) allowed to do this under U.S. law. They have an all American born crew, and are not required to sail "outside" the U.S. on their voyages. All other cruise lines must sail to Fanning Island and end up using at least 2 of the 7 days of the week. It really cuts into the time spent in the Hawaiian islands.
