Yesterday afternoon, on their website, Disney announced that all cruises on the Disney Magic are cancelled until June 7th because of the coronavirus. The Magic was scheduled to go to Europe in the middle of May, but because of the current situation, the late-May and early-June European cruises have been cancelled. The cruises on the Dream and Fantasy are still only cancelled until May 17th, but that's probably going to change.
All of the people affected by this suspension will have the choice of receiving a full refund or full cruise credit to be used in the next 15 months.
If necessary, the Magic cancellations will be extended past June 7th. The Dream and Fantasy cancellations will likely be extended as well. Be sure to check the Disney Cruise Line website for more information and the latest updates.
