Most people don't think of Hawaii as a popular cruise destination but it's the perfect way to experience all of Hawaii in just 7 days! Norwegian Cruise Line (NCL) offers year-round 7-day Hawaii cruises departing from either Honolulu or Maui. Extended length seasonal cruises to Hawaii are offered by Holland America Line and Princess Cruises from September until April departing from San Diego or Los Angeles. Additional cruises to Hawaii are available late spring and early fall on Carnival Cruise Lines, Celebrity Cruises and Royal Caribbean as ships reposition to/from Alaska.
