Carnival Liberty Review. Carnival Liberty Overview Updated By Ashley Kosciolek, Copy Editor(4.5) The 2,974-passenger Carnival Liberty launched in 2005 as the fourth of five ships in the line's Conquest class, the series that preceded the splashy Dream-class trio.
In fall 2011, Liberty became the first Carnival ship overhauled as part of the $500 million Fun Ship 2.0 initiative, a multi-year program focused on adding "signature" dining venues, bars and entertainment options to more than a dozen ships. Among Liberty's plethora of new offerings, passengers will find a candy store, four new soon-to-be signature bars (at two of which you'll find an iguana and a frog doing battle), comedians approved by George Lopez and burgers backed by the Food Network's Guy Fieri.
