Guests are invited to come as they are - fun for all, all for fun, they say - and everyone is made to feel right at home with comfy staterooms, attentive service, casual and elegant dining, plus a variety of bars and gathering places indoors and out. In a nutshell, Carnival is all about fun vacations at sea and ashore! A Carnival cruise features day and nighttime entertainment like stage shows, musical performances, deck parties, casinos and more (Like waterslides!). Continually growing since their founding in 1972, Carnival Cruise Line - “The World’s Most Popular Cruise Line” - now carries millions of passengers every year.
