With weather forecasters unclear about how steering currents will affect dangerous Hurricane Dorian, cruise lines are having to make plans for their Caribbean fleets without clear guidance.
Carnival Cruise Line
Carnival Cruise Line, the largest brand in the Caribbean, is still evaluating where a half dozen of its scheduled cruises will sail this weekend.
Those sailings are of a scheduled Sept. 1 departure of the Carnival Horizon from PortMiami and Sept. 2 departures of the Carnival Elation and Carnival Liberty from Port Canaveral, the Carnival Victory from PortMiami and the Carnival Sunshine from Charleston, S.C.
Carnival said it is possible that these cruises will not be able to return to those ports in time for departure, and that If the ports are closed, the ships will be in position to dock as soon as the authorities have reopened the ports. It also recommended that passengers sign up for text alerts.
Carnival is also modifying a number of itineraries due to the storm. The Carnival Sensation sailing of Aug. 31 will now visit Grand Turk on Sept. 2, Half Moon Cay on Sept. 3 and Nassau on Sept. 4. The Carnival Victory departure of Aug. 30 will replace a call to Nassau with a visit to Key West on Aug. 31 from 9 a.m. to 6 p.m.
Also, for the Carnival Miracle sailing on Sept. 1 from Tampa, Carnival anticipates a potential port closure that day, so this sailing will now operate as an eight-day itinerary, departing on Saturday evening, Aug. 31. It asks passengers to disregard their arrival appointments and make plans to arrive at the cruise terminal between 7 p.m. and 10 p.m. It said guests who cannot travel on the extended duration may cancel and receive a future cruise credit. Full details will be sent by email this evening.
Carnival also asks that guests on the Carnival Paradise departure on Saturday, Aug. 31 disregard their scheduled arrival appointments and plan to arrive between 10 a.m. and 1 p.m., after which time the ship will sail.
The following Carnival departures have not been modified and will sail as scheduled on Saturday, Aug. 31: the Carnival Magic from Port Everglades; the Carnival Ecstasy from Jacksonville; the Carnival Liberty and Carnival Breeze from Port Canaveral; and the Carnival Conquest from PortMiami.
Royal Caribbean International
Royal Caribbean International said it has changed the itinerary of the Navigator of the Seas cruise departing Aug. 30 so that it will return to Miami on Sept. 4 rather than Sept. 2. The ship will go to Nassau on Aug. 31, be at sea on Sept. 1, in Cozumel on Sept. 2 and at sea on Sept. 3.
The Navigator departure that is scheduled for Sept. 4 has been shortened to a three-day cruise that will visit CocoCay.
Likewise, the Mariner of the Seas departure on Aug. 30 from Port Canaveral is being extended until Sept. 4. The cruise will visit Labadee on Sept. 2 and be at sea on Sept. 3. The Mariner cruise from Port Canaveral departing Sept. 4 will be a three-day cruise to CocoCay.
The Empress of the Seas sailing that departed Miami on Aug. 24 has been extended until Wednesday, Sept. 4. Royal has added a call at Roatan on Aug. 31. The Mariner will then have two sea days and visit Nassau on Sept. 3, before returning to Miami on Sept. 4.
The Empress sailing scheduled for Sept. 1 will now depart on Sept. 4 and will be shortened to a three-day cruise visiting Nassau.
The Harmony of the Seas cruise that departed on Aug. 25 from Port Canaveral has been extended to return to Port Canaveral on Sept. 4, with additional days in Cozumel and at sea. The next Harmony cruise will now be a four-day trip to Labadee departing on Sept.4 and returning on Sept. 8.
Likewise, the Allure of the Seas sailing from Port Everglades is extended to Sept. 4 with additional stops at Roatan, Cozumel and days at sea, and the Sept. 4 departure will be a four-day cruise to Cozumel.
The Majesty of the Seas sailing from Port Everglades on Aug. 28 has been extended, and passengers will now visit Nassau and have a day at sea before returning on Sept. 4. The next cruise will be a three-day cruise to Nassau.
The three-day Symphony of the Seas departure from Miami on Aug. 31 is being extended to four days and will visit Costa Maya, Mexico, rather than Nassau. The scheduled Sept. 3 Symphony departure has been moved to Sept. 4 and will be shortened by removing a sea day.
Norwegian Cruise Line
Norwegian Cruise Line said the Aug. 25 sailing of the Norwegian Breakaway from Miami will be extended to a date to be determined because of Hurricane Dorian, which could be a Category 4 storm when it strikes Florida this weekend.
The Breakaway will overnight in Cozumel until Sunday and depart at 5 p.m. During this time, guests will have the option to conclude their cruise and arrange their return home or remain aboard. Guests who choose to end their cruise in Cozumel will receive a 25% off a future cruise.
Norwegian said it will provide an update on the anticipated return date to Miami by 8 p.m. or sooner on Friday. It will also provide an update on the next sailing at that time.
The Aug. 26 sailing of the Norwegian Sky from Miami will no longer call to Great Stirrup Cay, Bahamas, and instead will return to Miami on Friday, a day earlier than scheduled. Guests will have the opportunity to remain aboard until 7 a.m. Saturday. Due to the shortened cruise, guests will receive a 20% refund of the paid fare.
The Norwegian Sun departed from Port Canaveral on Thursday as scheduled. Calls to Nassau, Great Stirrup Cay and Freeport in the Bahamas have been canceled. Instead, the ship will spend a day at sea Friday and will call to Cozumel on Saturday. The ship will remain at sea on Sunday and is scheduled to return to Port Canaveral on Monday.
Disney Cruise Line
Disney Cruise Line said the Aug. 30 departure of the Disney Dream will become a five-night sailing with an expected return to Port Canaveral on Sept. 4. Anticipated calls include Cozumel on Sept. 1 and Castaway Cay on Sept. 3, depending on the storm's path.
The Dream cruise previously scheduled for Sept. 2 will become a two-night sailing, with an expected departure from Port Canaveral on Sept. 4 and return to Port Canaveral on Sept. 6. It will visit Disney Castaway Cay on Sept. 5, subject to storm damage assessment.
Guests who choose to continue with this sailing will receive a 50% refund and a $250 onboard credit per stateroom. Those who do not want to sail on Sept. 4 must call (866) 325-3905 or (407) 566-7032 by noon on Sunday, Sept. 1; those guests will have until Oct. 31 to choose a new sailing date.
The Aug. 31 Disney Fantasy sailing is unchanged.
MSC Cruises said the MSC Seaside is currently scheduled to depart PortMiami on Aug. 31, and the MSC Armonia is scheduled to depart PortMiami on Sept. 2. While at this time neither of these cruises have been canceled, guests scheduled to embark on either ship are encouraged to check MSC's website regularly for updates. MSC Cruises will update itinerary details for both ships upon receiving information related to the status of PortMiami.
