Carnival Destiny is a cruise ship that is owned and operated by Carnival Cruise Lines. Destiny spends her time plying the waters of theCaribbean. Upon entering service in 1996, she was the largest passenger ship ever built as measured by gross tonnage, and the first passenger ship larger than the 1940-built RMS Queen Elizabeth. She is the lead ship of the Destiny-class and has four similar sister ships: Carnival Triumph, and Carnival Victory sailing for Carnival Cruises and Costa Fortuna and Costa Magica sailing for Costa Cruises. The Carnival ships differ from her by the addition of extra balcony cabins on their Lido decks and various changes to placements and shapes of their public areas; the Costa ships have more dancing space and a smaller casino, as well as changes in locations of her public spaces.

As of August 2009, Roberto Leotta, of Italy, is the captain of Carnival Destiny.

Given a multi-million dollar refurbishment in 2005, Carnival Destiny features three pools, a variety of dining options, lounges, nightclubs, a casino, duty-free shopping and Spa Carnival.

The propulsion system consists of 6 thruster units, 3 forward and 3 aft, each with variable pitch propellers and 1760 KW motors. The electricity for the motors is provided by diesel engine generators.

Carnival Destiny has received more upgrades in 2010 such including pool-side TVs, and room renovations.

Currently Carnival Destiny offers 4 and 5 night Eastern and Western Caribbean cruises. Her sister ship, Carnival Victory, replaced Carnival Destiny in San Juan.
