The new season will be filmed on the 3,560-guest Royal Princess, the sister ship to Regal Princess, which appeared in the first run.
Tony Roberts, Princess Cruises’ vice president UK and Europe, said: "The first series of The Cruise was a great success for Princess and the cruise industry as a whole, so we are thrilled ITV has asked to come onboard again.
“We’re eagerly anticipating following Royal Princess as she sails around the Mediterranean and watching the onboard stories unfold to an audience of millions."
Paul Hamann, executive producer at documentary makers Wild Pictures, said: “Wild Pictures are delighted to be back onboard collaborating with Princess to make another series of The Cruise.
“Our team will be working hard filming over the summer to give our audience a tantalising taste of life aboard Royal Princess as it cruises round the Mediterranean.”
