MIAMI — Bookings are now open for a number of port-intensive cruises aboard Norwegian Cruise Line ships, including the Norwegian Jade, Norwegian Spirit and Norwegian Sun.

The cruise line has announced four new ports, including the new homeport of Athens for its 2020 season. Here are the highlights:

NORWEGIAN SPIRIT

Following a multi-million-dollar, bow-to-stern revitalization in January 2020, Norwegian Spirit will return to Asia for a series of itineraries.

From May 9 through Dec. 21, 2020, it will sail a mix of nine- to 15-day voyages that include four new ports of call for the brand. These include Beppu, Kumamoto, Niigata and Nagoya, Japan. The ship will also overnight in Tokyo and Kyoto (Osaka), Japan; Shanghai, China; and Hong Kong.

NORWEGIAN SUN

Following a three-year hiatus in the region, Norwegian Sun will return to Alaska on May 21, 2020, joining Norwegian Bliss, Joy and Jewel. It will offer the brand’s most extensive itineraries in the area with nine- to 12-day voyages from Seattle with calls to Sitka, Glacier Bay, Hubbard Glacier, Holkham Bay, Juneau and Ketchikan, Alaska, as well as a stop in Victoria, B.C. Guests can also spend a full day exploring Icy Strait Point.

Norwegian Sun is fresh off a bow-to-stern renovation in April 2018 that included refreshed staterooms and public spaces, as well as three new venues: Los Lobos Cantina, Bliss Ultra Lounge and Spinnaker Lounge.

NORWEGIAN JADE

Beginning Sept. 8, 2020, Norwegian Jade will offer a variety of one-way, 10- to 11-day Greek Isles, Italy and Mediterranean cruises departing or returning from Barcelona, Venice and Athens, where the company will homeport for the first time. Calls include Monte Carlo, Florence/Pisa, Rome, Naples and Messina in Italy, and Olympia, Santorini, Rhodes and Mykonos in Greece, as well as Kusadasi, Turkey.
