Our friends that haved used Cunard ships as a way to cross the Atlantic several times, recently cruised with us on Celebrity for the second time. They said that they found Celebrity to be more fun and less stuffy. Celebrity may not be perfect , but most people I encouter on their ships are repeat cruisers. Some people feel that they are on a British ship when they sail on Cunard, but I find that puzzling. Cunard is owned by Carnival, and their new ships are built in France.
