Fans of the Carnival Cruise Line are celebrating. That's right, literally.

The maiden voyage of the line's much-awaited Carnival Celebration will take place on Sunday.

The 15-deck high ship is a sister vessel to Carnival's giant, one-year-old Mardi Gras. A decktop roller coaster is one of the most unusual attractions on a cruise ship.

The largest ship ever to sail for Carnival is a tie between the two ships.

The next biggest Carnival ship is the 3-year-old Carnival Panorama, which is larger than all but 11 other vessels in the world.

There is a roller coaster on the top deck. Bolt is a roller coaster with an 800-foot track. Its vehicles can go as fast as 40 miles per hour.

The ships are capable of holding up to 6, 630 passengers. Royal Caribbean's Wonder of the Seas is the world's largest cruise ship and can hold 7,064 passengers.

Carnival Celebration will have a much larger array of suites and a giant water park than previous Carnival ships. The vessel will not be a copy of its sister.

The main interior area is called Celebration Central. There will be multiple food and entertainment venues on the three decks of the Grand Central area on Carnival Celebration.

It will offer daytime ocean views and nighttime shows on its stage, which has more color-changing lights than the original, to be precise. The first thing passengers will see when they board the ship is the confetti.

The development of ships on the scale of Carnival has been a big deal for the company. The line had resisted the trend among major brands to build ever- bigger vessels that offer a megaresort at sea experience.

The last new vessel from Carnival didn't make the top 40 list of biggest ships.

There are six to eight day voyages to the Bahamas and the Caribbean planned for the vessel. Not including taxes and fees, fares start at $449.

The oldest and smallest ship in Carnival's fleet was retired four weeks ago.

There is another Carnival ship headed for the scrappers.

Carnival is adding a second ship to its fleet this month with the arrival of Carnival Luminosa, a 13 year old vessel that was previously in the Costa Cruises fleet. The ship used to be known as CostaLuminosa.

The line's fleet will increase by one ship to 24 ships with the arrival of Carnival Celebration and Carnival Luminosa.

Carnival will take on two more Costa ships in the next two years as it pulls back on cruises in China.

A third ship in the same series, called Carnival Jubilee, will be built in the same shipyard as Carnival Celebration. The shipyard built many things.

Carnival Celebration will be sailing out of Miami for the first time on November 21st.
