Carnival cruiseline is the second largest cruise company in the world, they have a lot of ships and many kinds of food. There are a lot of activities to do on board, the newest ship of the company called the Mardi gras, even have a roller coaster, the first at sea! The company added a new ship to their fleet a few months ago, called the Carnival celebration this ship does also offer a rollercoaster! The second at sea! The shipping company is now building a new cruise ship, this ship is called the Carnival jubilee. This ship will probably sail next year. The company offers very cheap cruises and the service is very good, but I advise you to take a cruise on one of the newest ships, which are:
