Key Aspects:
- Norwegian Sun will remain in Copenhagen for two extra nights for required maintenance during her September 23, 2026 sailing.
- The ship’s safety is not impacted but it is not confirmed if this maintenance is related to propulsion repairs a few weeks earlier.
- The visit to Oslo and a sea day are now changed to accommodate the extended Copenhagen stay, but no other ports are impacted.
Guests booked on the September 23, 2026 departure of Norwegian Sun will be getting a prolonged stay in the departure port of Copenhagen, Denmark, while the ship remains docked for maintenance. Norwegian Cruise Line has sent email notifications of the change and how the rest of the 10-day itinerary is impacted.
“To support required maintenance, which does not affect the safety of our ship or that of our guests and crew, our highest priority, our visit to Oslo, Norway, and one scheduled day at sea have been replaced with two overnight stays in Copenhagen, Denmark,” the email explained.
Embarkation will still take place as scheduled on Wednesday, September 23. The cruise line is firmly reminding guests that they must still adhere to their pre-selected arrival time window, even though the ship will not be departing Copenhagen that evening as originally planned.
“Although the ship will remain in Copenhagen overnight, guests are still required to arrive at the terminal during the designated arrival window selected during Online Check-In,” the email stated. “To help ensure a smooth embarkation experience for all guests, pre-selected arrival times will be strictly enforced.”
Because the 1,976-guest ship will remain docked in Copenhagen until Friday, September 25, the visit that was planned for Oslo, Norway on Thursday, September 24 from 10 a.m. to 9 p.m. is now cancelled. Likewise, Friday will no longer be the day at sea that was originally scheduled.
Instead, Norwegian Sun will depart Copenhagen at 5 p.m. on Friday and make for Warnemunde (Berlin), Germany. Because the two ports are just over 100 miles apart, the ship should be able to reach Warnemunde easily for the planned visit from 6 a.m. to 8 p.m. on Saturday, September 26.
The rest of the itinerary is not changed at this time. Norwegian Sun will visit Gdynia, Poland from 1:30-9:30 p.m. on Sunday, September 27; Klaipeda, Lithuania from 10 a.m. to 5:30 p.m. on Monday, September 28; Riga, Latvia from 9:30 a.m. to 5:30 p.m. on Tuesday, September 29; Nynashamn, Sweden from 8 a.m. to 6 p.m. on Wednesday, September 30; and Tallinn, Estonia from 11 a.m. to 8 p.m. on Thursday, October 1.
Norwegian Sun will arrive in Helsinki, Finland for debarkation at 7 a.m. on Friday morning, October 2.

Guests booked on the now-adjusted journey will receive a $100 non-refundable onboard credit, which will be split between the first two guests booked in each stateroom. Norwegian Cruise Line is providing this credit in appreciation for guests’ understanding of the change.
Regular Maintenance Not Explained
While the email notification cites “required maintenance” as the reason for the change, no further details have been provided about which system needs the work. The cruise line does note that Norwegian Sun‘s safety is not impacted in any way.
This is not, however, the first time recently that Norwegian Sun has required an extended stay in Copenhagen. Just a few weeks ago, Cruise Hive reported that two Baltic itineraries were disrupted due to the need for propulsion repairs that were carried out during unplanned extended stays in Copenhagen.
Norwegian Cruise Line has not stated whether the new need for maintenance is related to the prior propulsion repairs.
Because cruise ships are complex machines that are running 24 hours a day, every day, ongoing maintenance is critical to keep every system functioning smoothly.
Every ship has technicians and engineering teams constantly working to keep the ship at its best, but some systems need more intensive repairs that can only be done while the ship is docked or even in dry dock.
Norwegian Sun is finishing her service with Norwegian Cruise Line over the next year. Cruise Hive reported in April 2025 how the ship, along with her fleetmate Norwegian Sky, has been chartered long-term to Cordelia Cruises and will join that line permanently in late 2027.
Before she leaves the NCL fleet, Norwegian Sun will finish her northern European season in mid-October 2026, then move to Miami to spend winter in the Caribbean. In April 2027, she will return to Europe for a final Mediterranean season with departures from Ravenna and Civitavecchia (Rome) until early September.
