A typical cruise from Los Angeles to Alaska is significantly longer than the standard week-long trips departing from Seattle or Vancouver, generally spanning 10 to 14 nights. Because Los Angeles is much further south, the ship requires at least two full days at sea to reach the first Alaskan ports of call, such as Ketchikan or Juneau. Most itineraries offered by lines like Princess Cruises or Holland America are "round-trip" voyages that cover over 4,000 miles. These cruises often include scenic cruising through the Inside Passage and Glacier Bay National Park, along with stops in Victoria, British Columbia, to satisfy international maritime laws. For travelers, this means a more relaxing pace with several "Sea Days" at the beginning and end of the trip, allowing for full enjoyment of the ship's amenities before reaching the rugged wilderness. While some "repositioning" cruises might take 7 to 9 days to go one-way from LA to Whittier or Seward, the vast majority of consumer-facing round-trip products from San Pedro or Long Beach are 12-day adventures.
