As the number of people in the United States infected with the pandemic continues to rise, Disney Cruise Line has decided to extend their new departure suspension through April 28.
In an official statement on the Disney Cruise Line Website, the company writes:
With the wellbeing of our Guests and team members as our top priority and in line with direction from health experts and government officials, Disney Cruise Line has decided to extend the suspension of all new departures through Tuesday, April 28, 2020.
The notice states that guests who are currently booked on affected sailings will be offered the choice of a cruise credit to be used for a future sailing within 15 months of their original sail date or a full refund. Guests and travel agents will receive an email from DCL outlining details and next steps.
Guests who booked their reservation through a travel agent should contact them directly with any questions. Those who booked directly with Disney Cruise Line and have questions after receiving their email from us should call us at (866) 325-2112 or (407) 566-3510.

The credit is non-refundable and standard prevailing rates will apply. Guests who booked their reservation through a travel agent should contact them directly. Those who booked with Disney Cruise Line may call us at (866) 325-2112 or (407) 566-3510.
