Royal caribbean is the largest cruise company! The shipping company has a very large fleet, including large and small ships. The company is the best company for children! Anyway on many of the ships you will find slides and other activities for your children. I am a big fan of the Oasis class ships, this is the largest class cruise ship in the world! This will change next year because then the Icon of the seas (also a ship from Royal caribbean) will take over the title of the biggest cruiseship in the world! The oasis class ships are very large and have zip lines, water parks, surf simulators, a kind of shopping mall, a park with real plants and much more. I must say that the Allure of the seas has no slides, and is in the oasis class. The company is busy with adding new ships to the fleet, in 1 year the Icon of the seas and the Utopia of the seas will arrive! The food on board is very good and i definitely recommend you to take a cruise with the shipping company! I recommend that you take a cruise on one of these ships: 

Icon of the seas

Oasis of the seas

Allure of the seas

Symphony of the seas 

Harmony of the seas

Utopia of the seas

Wonder of the seas

Odyssey of the seas 

Anthem of the seas

Ovation of the seas 

Quantum of the seas
