The new programme, which will take place between April and October 2023 in Southampton, will include time onboard the line’s newest ships, Arvia and Iona, as well as Britannia, Ventura, Aurora and Arcadia.
The visits will offer agents a tour of the cabins, entertainment venues and dining options, as well as a three-course meal in one of the restaurants onboard.
Agents can now book to visit Ventura on 22 April and 15 July, Aurora on 2 May, Iona on 3 and 10 June and 8 July, and Arvia on 25 June.
Future dates will be available to book via the Shine Rewards Club soon, and include Arcadia on 29 August, Iona on 2 and 23 September and 7 and 21 October, Arvia on 3 and 17 September, and Britannia on 19 October.
P&O Cruises director of sales, Ruth Venn, said: "We could not be more excited to bring back ship visits for travel agents this year.
"With more than 1,000 spaces available, including on our newest ship, Arvia, it is the perfect opportunity for agents to experience our ships for themselves and everything that’s included in the cost of a P&O Cruises holiday."
