Life onboard
What it actually feels like to sail Iona— entertainment, food, and the crowd you'll find onboard.
Entertainment
You'll find a busy roster of evening productions in the main theater—theatrical shows with live bands, comedy clubs with touring comedians, and a nightclub that stays lively past midnight. During days, street performers and acoustic musicians pop up in corridors and lounges, and there's usually a karaoke or trivia session running somewhere. The vibe skews accessible and participatory rather than elaborate, with entertainment that works equally for families and groups.
Food & dining
The main dining room offers a traditional fixed-seating experience with nightly menus ranging from acceptable to decent, while specialty venues scatter around the ship—an Asian fusion spot, a steakhouse, a Mediterranean grill—each with a modest cover charge. The buffet is expansive and reliably stocked, though peak breakfast and dinner hours create crowding. Fresh pasta, seafood stations, and properly executed classics stand out; don't expect fine dining but you won't feel shortchanged.
Atmosphere
Iona caters to multi-generational British families and retirees who want contemporary cruise comfort without formality—think smart-casual rather than dress codes. The ship balances supervised kids' clubs and family zones with adult-only pool decks and cocktail bars, so you can cruise with grandkids and still find quiet corners. The overall tone is inclusive, laid-back, and unapologetically British, with a modern-casual energy that feels like cruise vacationing for people who cruise regularly.
The ship & service
A closer look at P&O as a line, Iona as a ship, and the service and deck quality to expect onboard.
- The line
- P&O Cruises is a mainstream British line aimed at UK guests who want familiar food, sterling pricing, and departures from Southampton without flying. It sits in the mid-market tier alongside the likes of Princess and MSC, best for British families, couples, and retirees who prefer a relaxed, unstuffy atmosphere over formal luxury or American-style mega-resort cruising.
- The ship
- Iona is one of P&O's newest and largest ships, a 2020-built mega-vessel carrying around 5,200 guests, so it feels expansive and resort-like rather than intimate. As a modern LNG-powered ship in the Excellence class, it leans into contemporary design with a multi-deck atrium as its social hub and a broad spread of bars, lounges, and family zones across the upper decks.
- Service
- Service is solid mainstream-tier rather than personal or anticipatory; with passenger numbers north of 5,000 and a typical mega-ship crew ratio, expect efficient, friendly delivery in dining rooms and bars but queues at peak times and limited recognition outside of loyalty-tier guests. It is high-volume hospitality done competently, not bespoke attention.
- Decks & spaces
- As a 2020 build the ship still feels current, with multiple pool decks including adult-only zones, a wraparound outer promenade area, and a tall central atrium used for daytime performances and evening drinks. Materials and finishes are contemporary mainstream-tier rather than premium, and general upkeep is good given the ship's relatively young age and no major refit yet required.

Z-normalized corrects for reviewer bias (every reviewer re-centered onto their personal scale). Raw average uses simple mean across the broader pool including stddev=0 reviewers. The 20-point gap is the rating-inflation signature for this title — the casual crowd liked it more than discriminating reviewers (a classic inflation pattern).
