Carnival Cruise Lines is one of the largest and well-known operators at sea. Their fun-filled itineraries are complimented perfectly by an impressive fleet of ships, each of which features some fantastic facilities for every member of the family. From slick water slides and even slicker evening shows to restaurants with something for all tastes, whichever vessel you choose you'll have made the right decision.

Although they predominantly offer Caribbean cruises from the coasts of the USA, Carnival also boasts fantastic sailings throughout Europe, Australia and New Zealand. There are 23 ships in total, with more being added every year, providing innovative experiences such as the SkyRide bikes, Sky Zone trampoline park and IMAX cinemas. Plus, if you want some time away from the kids (or don't plan on bringing them at all), the adults-only Serenity Retreat will welcome you with open arms.

When the fun has to end, you'll be relieved to retire to your comfortable stateroom. Standard perks include climate control, a room steward and bathrobes, but upgrade to a suite and you can make the most of priority check-in and dinner reservations. Need a specific stateroom to suit your group's needs? There are some great options to choose from. Go Family-Friendly to sleep up to five people and enjoy a second bathroom, opt for a Cloud 9 Spa Stateroom for extra relaxation, or select one of the rooms that put you in prime position for specific venues such as the Family Harbour Lounge or Havana Bar and Pool.
