P&O splits its fleet by audience more than by size
More than most lines, P&O's ships are built around who is meant to sail them. Iona, Arvia, and Britannia target families and a broad mix of ages, while Arcadia and Aurora have long been marketed specifically to adults, making audience the first filter to apply.
Iona and Arvia: P&O's LNG-powered family flagships
These are P&O's newest and largest ships, powered by liquefied natural gas, with extensive family pools, entertainment districts, and the widest dining variety in the fleet.
Britannia: the established family-friendly mid-size ship
Britannia carries much of the same family-oriented programming as Iona and Arvia at a smaller scale, often at a better price and with easier navigation for families with young children.
Arcadia and Aurora: built for adults
These two ships have long been positioned as P&O's adults-focused sailings, with a quieter, more traditional atmosphere, glass-ceiling atriums, and specialty venues like Marco Pierre White's Ocean Grill on Arcadia. Always confirm the current age policy for your specific sailing before booking, since P&O has been adjusting this on select dates.
Why a UK homeport is a bigger factor with P&O than most lines
The large majority of P&O sailings depart from UK ports like Southampton, letting British travelers avoid flights entirely. For many P&O guests, this convenience matters as much as any onboard feature when comparing ships.
Which P&O ship is best for a family with young children?
Iona or Arvia, for the newest kids' clubs and the widest range of family pool space. Britannia is a solid second choice for families who want a smaller, easier-to-navigate ship.
Which P&O ship is best for a quiet couples' getaway?
Arcadia or Aurora, specifically on sailings still operating under their traditional adults-focused policy, confirm this directly with P&O for your travel dates, since it has been changing on select departures.
How does P&O differ from Cunard, its former sister-in-history?
P&O is noticeably more casual and family-oriented day to day than Cunard, without the same formal-night intensity, making it a more approachable entry point into British-flagged cruising.
Bottom line
Start with audience, family-focused Iona, Arvia, and Britannia, or the more traditionally adult-focused Arcadia and Aurora, then let a UK homeport's convenience help decide between ships that fit your group.
