Their ships are brilliantly organised floating resorts or adventure playgrounds for kids and big kids, where you'll be constantly stimulated by everything, from the colourful décor to the Las Vegas-style casinos.
There's something to do 24 hours a day from playing golf with a pro to art auctions and deck parties. You can even try a spot of ice-carving!
Particularly well run is Camp Carnival, the kids' programme from ages 2 to 17, where imaginative highlights include talent shows, marine biology and dance parties. That's if you can keep them off the zigzagging waterslide, of course!
Carnival's Total Choice Dining means you can mix and match your meals whether you want a fabulous on-deck buffet, a health conscious Spa Carnival menu or seafood at the reservations-only Supper Club.
Evening entertainment is an all-American experience with Broadway-inspired stage shows and Las Vegas-style musical reviews. Or for something more low-key there are sports and piano bars, as well as late-night lounges.
And if you fancy a quiet night in, staterooms are notable for their spaciousness and even here there's plenty to entertain with a TV playing first-run movies and complimentary room service.
Carnival Cruise Line want to take you to "A new level of excitement" and quite frankly if you want to relax, stay home, because this is one holiday where you won't get bored!
