The class consists of several series (subclasses) of sister ships, most of which were built by Fincantieri in Monfalcone and Trieste, northern Italy.

Ships of the later subclasses are based on the Grand class, but have modifications such as additional decks and varied placement of facilities such as the nightclub and restaurants.

Caribbean-class vessels also introduced a poolside theater, which was later added to other Princess ships.

The second Ventura-class ship is MS Azura, launched in March 2010 which has a modified stern.

Azura is also the only P&O Cruises ship to feature a poolside theater style outdoor screen.
