SEATTLE — Two Holland America Line ships, Eurodam and Amsterdam, will say aloha to the islands of Hawaii starting this fall.

Nine extended cruises running from fall 2018 through spring 2019 will offer 16- to 20-day sailings that include four Hawaiian ports.

Hawaii sailings depart from Seattle, Vancouver and San Diego and Los Angeles.

Most itineraries feature an overnight call in Honolulu, where guests have extra time to visit Pearl Harbor, relax on Waikiki Beach, take in the views from Diamond Head State Monument or spend the evening experiencing traditional Hawaiian food and entertainment at a luau. The cruises also call at Hilo, Nawiliwili and Lahaina, with most adding a call at Kona.

To kick off the season, Eurodam departs Seattle Sept. 29, 2018, for an 18-day Circle Hawaii cruise that calls at Victoria and Vancouver before heading to the Hawaiian ports of Nawiliwili, Honolulu, Lahaina and Hilo. Guests also can choose to embark two days later, Oct. 1, and sail roundtrip from Vancouver on a 16-day sailing.

A second 18-day voyage is available aboard Eurodam Nov. 11, sailing roundtrip from San Diego. Guests will visit the same Hawaiian ports, as well as calls at Kona and Ensenada, Mexico. A comparable itinerary is available on Amsterdam’s 17-day Hawaii Holiday cruise, sailing roundtrip from L.A. Dec. 21.

In 2019 three similar itineraries are available aboard Eurodam, including two 17-day sailings departing Feb. 3 and Feb. 20, as well as a 16-day sailing embarking April 13. Cruisers interested in extending their vacation can lengthen the April 13 cruise and disembark in Vancouver after visiting Victoria for a 20-day voyage.

Guests who wish to dive deeper into the South Pacific can select Eurodam’s 28-day Hawaii, Tahiti and Marquesas voyage March 9, 2019. Sailing roundtrip from San Diego, cruisers will enjoy visits to six ports in French Polynesia, including overnights in both Bora Bora and Papeete, as well as two ports in Hawaii and a call at Fanning Island.

Cruisers can further their exploration of the region on the Amsterdam’s 51-day Tales of the South Pacific voyage Oct. 28, 2019. Sailing roundtrip San Diego, the ship will visit Hawaii, Tahiti, as well as calls in America Samoa, the Cook Islands, Fiji, Vanuatu and Tonga.
