In Carnival's Mardi Gras cancellation letter, they mention their upcoming series of special sailings to celebrate Carnival's 50 Years of fun that would be released in January. Has anyone heard anything about these itineraries yet? We decided to wait to see what the offerings would be for these sailings to rebook. They said that the cancelled Mardi Gras guest would be the first to get information, but I have not heard anything yet.
