Parents, you’ve gotta be quick with this one…
P&O Cruises has unveiled a limited-time Early May Bank Holiday promotion that allows additional guests to sail from just £49 per person on selected summer 2026 cruises.

The offer, announced today on 1st May 2026, applies to third and fourth guests sharing a balcony cabin with two full-paying adults on selected voyages departing from Southampton.
It is available on cruises of seven nights or longer sailing between 7th June and 22nd August 2026.
The promotion is only available for new bookings made by 5th May 2026 and is subject to availability.
The deal aims to encourage families and groups to book summer sailings, with peak school holiday departures included in the offer. While P&O Cruises often offer reduced prices for the third and fourth guests in a cabin, they are usually only in term-time.

P&O Cruises Are Great For Families
I’ve taken my kids on all of P&O Cruises family ships and they’ve always had a great time. They love the kids clubs, pools and the variety of family-friendly entertainment.

The line is one of the only cruise lines to allow two-year-olds into the kids clubs without parents, and there’s also a complimentary night nursery for under fives, making it a great option for those with younger children too.
Cruise fares with P&O Cruises include accommodation, full board dining, access to pools and entertainment such as theatre shows and live music, as well as complimentary children’s clubs.
