When i worked for International Martime Security [IMS] my first ship was part of the Premier Cruise Lines fleet, Oceanic. She 'lived' from 1963 through to 2012, not a bad life and an interesting career if you look her up on Wikipedia.
However, during my time onboard we were linked to Disney in that you could have 4 days at Walt Disney World in Orlando and 3 days on Oceanic, which sailed out of Port Canaveral, or visa versa. As we were linked to Disney we had a selelction of Disney charactors [critters] onboard who had 'appearance' schedules around the ship. After a couple of months this link changed to Universal as this was when Disney first announced they were going into the cruise business themselves. The joke onboard at this time was that 'we're not even a Micky Mouse organisation now!'
Some years later, when i was on Vistafjord and we were in Venice, some of the ex Cunard engineers who had gone over to Disney used to come onboard as they were overseeinng the new build of the first Disney ship in the Fincantiari shipyard in Venice.
