I don't see the Magic going to Alaska, based on its current schedule that ends in Port Canaveral on May 19. That means the first Alaska cruise wouldn't begin until ~ 3 weeks later, and that cuts into
DCL's lucrative Alaska season too much. Besides - other cruise lines have recently had MAJOR dry docks on the west coast.
The Magic's last Bahamas cruise ending on May 19 in Port Canaveral fits its Transatlantic cruise schedule. It is supposed to arrive in Madeira on May 27, 2014, according to a tour provider I contacted about a 2013 tour. It would probably do this:
May 19 - depart from Port Canaveral
May 20 -
Castaway Cay
May 21-26 - 6 sea days
May 27 - Funchal, Madeira
If I were a betting woman, I'd bet the Magic will go to Europe and the Wonder will go to Alaska - just as they will do in 2013.
