The six-part ITV documentary will air on Thursdays at 8.30pm from January 12.
The show was filmed onboard Royal Princess during its Mediterranean sailings this summer.
Downton Abbey actor Hugh Bonneville will return to voiceover duties for the programme.
Each episode will offer viewers an insight into the day-to-day running of the 3,560-passenger vessel and its 1,400-strong crew.
Tony Roberts, Princess Cruises’ vice president UK and Europe, said: "Following on from the success of series one, which averaged 3.5 million viewers and has received a National Television Award nomination, we are excited to see what series two has in store for Royal Princess’ crew and guests.”
