(6:12 p.m. EST) -- One of Princess Cruises' biggest cruise ships will head to Alaska in 2019, marking the highest passenger capacity the line has ever had in the region.

The 3,600-passenger Royal Princess will be one of seven ships sailing Alaska from May to September 2019; most of the itineraries will include a visit to Glacier Bay National Park. In addition to a variety of cruises ranging from seven to 12 nights, passengers can choose from 23 cruise tours (a land tour that can be added to the beginning or end of a trip).

Here's a breakdown of the 2019 Alaska itineraries:

  • Seven-night Voyage of the Glaciers cruise, between Vancouver and Whittier: Available on Royal Princess, Golden Princess, Coral Princess and Island Princess, this cruise includes a stop at both Glacier Bay National Park as well as either Hubbard Glacier or College Fjord. Northbound sailings on Island Princess also include Icy Strait Point.
  • Seven-, 10- and 12-night Inside Passage cruises, from Seattle, San Francisco, Los Angeles and Vancouver: Seven-night sailings from Seattle are available on Ruby Princess and Star Princess; 10-night sailings from San Francisco are available on Grand Princess; 12-night sailings are available from Los Angeles on Royal Princess, Ruby Princess and Star Princess; and 12-night sailings from Vancouver are available on Coral Princess, Island Princess and Golden Princess.

Seven-night cruises on Ruby Princess will visit Glacier Bay National Park, while seven-night cruises on Star Princess will call at Tracy Arm Fjord. All cruises from Seattle will feature a late night in Juneau.

For those who wish to sample an Alaska Princess cruise, two four-night sailings on Golden Princess and one five-night sailing on Island Princess also are available.

In celebration of its 50th anniversary in Alaska, Princess Cruises will allow a reduced deposit (50 percent off) for all booked cruisers from North America, Asia and Australia. The 2019 cruises and cruise tours go on sale December 14, 2017.

Royal Princess will replace 3,080-passenger Emerald Princess, which is slated to reposition from Alaska to the Mediterranean 2019, for the line's biggest Europe season.
