Galveston - Carnival Magic:
Right now the Magic does 7 day voyages and goes to Grand Cayman. The Port of Grand Cayman's website shows the Magic docking May 1, 2014, but it does not appear on the schedule for the rest of the year when other Carnival ships do. I don't know what this means. If you want to see what I am refering to (http://www.caymanport.com/shipschedules.php). I did the start date in the search as May 1, 2014 and ending the search result with December 31, 2014.
New Orleans - Carnival Sunshine:
When I visited the Port of New Orlean's website I searched for cruises in June 2014 and the port only shows the Elation docking. Here is the link:
http://corelserver1.portno.com:8082/cruisemain.htm . Search at the top for June 2014.
Hopefully, neither of these ships are changing homeports as I enjoy cruising from Galveston and New Orleans. After seeing this it makes me think that they are decreasing capacity or replacing ships.
Please share any information you have. I am trying as hard as possible not to speculate, but thought I would share my findings in light of today's itinerary changes.
