By Cruise Advisor Editorial Team · Updated 2026-10-15 · 11 min read

P&O Iona departing Southampton with SkyDome and Grand Atrium visible

Planning a 2026 sailing on P&O Iona? This UK-focused review explains who the ship suits, what’s included, how dining works, and the real trade-offs of cruising a very large ship from Southampton.

If you are searching for a clear, UK‑focused P&O Iona review 2026, this guide brings together what P&O officially states about the ship with an editorial verdict for families, couples and first‑time cruisers. Iona is one of the biggest cruise ships sailing from Southampton, launched in 2021 and designed with British tastes in mind. She features the light‑filled SkyDome and a multi‑level Grand Atrium, around 30 bars and restaurants, four pools and 10 entertainment venues, aiming to balance choice with a relaxed, contemporary feel. Because policies and onboard offerings can change, use this review as a decision framework and always verify key details on P&O’s website before booking.

Our 2026 verdict by traveller type (editorial)

  • Families: Compelling if you value sea days with weather‑proof spaces like SkyDome, flexible dining options, and a big choice of things to do. The scale helps keep everyone occupied, but managing meal and show times matters.
  • Couples: A solid choice if you want lively evenings, bar‑hopping and a modern British atmosphere. Seek out quieter nooks in the Grand Atrium and lounges during off‑peak times for a calmer vibe.
  • First‑time cruisers: Designed with newcomers in mind. Clear signage, familiar dining formats and a homeport in Southampton remove much of the faff. Just be ready for the scale—planning goes a long way.

How Iona’s size shapes your holiday (editorial assessment)

Large‑ship cruising brings trade‑offs. On the plus side, more venues mean more choice at meal times and in the evenings, and the SkyDome reduces weather dependency on sea days—a big win for UK departures. The flip side is that popular spaces can feel busy at peak times, and getting from A to B takes more walking and a little planning. If you’re happy to plan your day with the ship’s programme, you gain maximum variety without feeling rushed.

Embarkation and sailing from Southampton in 2026

One of Iona’s UK‑friendly advantages is sailing from Southampton, removing the need to fly. In 2026, aim to build your embarkation day around the arrival time P&O assigns or recommends for your booking. Give yourself margin for motorway or rail delays, keep travel documents and luggage tags handy, and review P&O’s latest pre‑boarding guidance a week before departure in case procedures have changed. If you plan to park or arrive by rail, factor in the short transfer from station or car park to your allocated cruise terminal and allow time for security and check‑in. Families should prepare hand luggage with day‑one essentials—swimwear, medications, snacks for little ones—so you can start enjoying the ship even if checked bags take time to reach your cabin. As with all operational details, check P&O’s current Southampton and embarkation guidance before you set off.

Cabins and accommodation: what to expect (editorial)

Iona offers a range of cabin types, from more economical interior options through to higher‑space categories. Balcony accommodation exists alongside other stateroom types, and some configurations on large family‑oriented ships can include inter‑connecting doors and additional bedding options; however, always verify exact categories, capacity and layouts on P&O’s deck plans for your specific 2026 sailing. The most practical way to choose is to prioritise location first—proximity to lifts, pools or quieter zones—then match that to your budget and desired space. On a ship of this size, a few metres closer to the spaces you’ll use most can make your daily routine noticeably smoother.

  • Study the deck plans and note the vertical “stacks” of lifts you’ll likely use daily.
  • If you are sensitive to noise, avoid cabins directly above or below major venues where late shows may run.
  • For families, verify whether inter‑connecting or additional‑berth options are available on your sailing before you book.
  • If you are new to cruising, many travellers prefer mid‑ship and lower decks for a more stable feel.
  • Check the walking distance to the SkyDome or pools if you plan frequent swims.
  • Confirm accessibility features and cabin measurements with P&O if mobility is a consideration.

    Included dining on Iona: how it works in 2026 (facts with guidance)

    P&O’s dining information indicates a mix of included dining options alongside speciality venues that carry an extra charge. The balance between included and extra‑cost experiences is central to budgeting on a big ship. For most travellers, the simplest approach is to plan on using included dining as your default, then add a speciality experience or two as a treat. As with any cruise, what is included can vary by sailing and date, so cross‑check P&O’s dining page in 2026 to see the current list of included options and any booking requirements.

    Speciality dining: when is it worth paying? (editorial)

    Speciality venues can add variety and a sense of occasion. They can be worthwhile if you are celebrating, seeking a quieter dinner, or keen to sample a particular cuisine. On large ships, these venues may be smaller and therefore more intimate than the main included spaces. The best value comes when you choose one or two speciality meals that align with sea days or evenings when the main dining rooms are busiest. Confirm availability and pricing with P&O for your exact 2026 sailing before committing.

    1. Make included dining your default and save speciality for 1–2 nights.
    2. If reservations are needed, book early, then adjust on board—plans often firm up once you are on the ship.
    3. Eat slightly earlier or later than the rush to reduce queueing and enjoy a calmer meal.
    4. On sea days, consider a relaxed late lunch and a lighter evening to avoid peak pressure entirely.
    5. Check your daily planner for any casual pop‑ups that are included—these can be quieter and great value.
    6. Ask P&O before sailing how dietary needs are handled across included venues.

      Bars and lounges: planning your evenings about 30 venues

      P&O lists roughly 30 bars and restaurants on Iona, giving you an enormous amount of choice. The trick in 2026 is to map your evening around the show or live music you most want to see, then select a nearby bar so you are not crossing the ship at peak times. The Grand Atrium is designed as a social heart with multi‑level views and seating, great for a pre‑ or post‑dinner pause. If you expect to purchase a lot of beverages, read our Iona drinks package guide 2026 before you sail so you understand how packages work and what usage would make them worthwhile for you. As always, confirm the latest package details with P&O directly in 2026, as inclusions and rules can change.

      Entertainment and activities across 10 venues (facts and editorial)

      P&O notes that Iona offers 10 entertainment venues, which typically means multiple production spaces, lounges and live‑music spots. On a ship this size, the nightly programme is designed to spread guests across different shows and styles, giving you options whether you prefer big theatre performances or more intimate acts. The editorial reality of big‑ship entertainment is that early‑evening performances can be popular; if there are multiple show times, you can often avoid the busiest slot by going earlier or later, then enjoying a quieter bar afterwards. Check your onboard planner as soon as you embark and identify two or three “must‑see” items to anchor your evenings.

      Pools, SkyDome and family‑friendly spaces (facts and editorial)

      P&O states that Iona has four pools, and the glass‑covered SkyDome provides a versatile, weather‑resilient space for daytime relaxing and evening events. For families, the SkyDome is especially useful on cooler or breezier sea days common on UK‑departing cruises. Expect the most popular pool areas to be busiest in the middle of the afternoon; you can often find a calmer hour pre‑lunch or in the late afternoon. If a particular pool or loungers matter to you, plan to arrive early, especially on sea days.

      Families: is Iona good in 2026? (editorial)

      Yes—if you value choice and flexible, weather‑resilient spaces. The combination of four pools, multiple dining venues and the SkyDome makes it easier to keep different ages happy without everyone needing to do the same activity. The trade‑off for families is that peak‑time crowds can develop around popular venues. Solve this by making small timing tweaks—earlier breakfasts on sea days, slightly later lunches after the midday rush, and planning a short quiet break mid‑afternoon before the evening picks up. For sleeping arrangements, verify cabin capacities, inter‑connecting availability and cot policies with P&O for your exact 2026 sailing.

      Couples: finding calm on a lively ship (editorial)

      Iona is well‑suited to sociable couples who enjoy exploring bars and catching different styles of live entertainment. To keep the experience balanced, rotate high‑energy evenings with quieter nights. Scope the Grand Atrium and lounges during embarkation day to identify favourite corners. Consider booking one speciality dinner for an occasion and otherwise leaning on included venues when they are less busy. Early‑in‑the‑voyage shows can be less crowded, and late‑evening strolls through the Atrium often feel more serene.

      First‑time cruisers: confidence without the faff (editorial)

      Iona’s British focus and Southampton homeport are helpful for first‑timers in 2026. The core decision is whether you want a ship with maximum choice or a smaller, quieter vessel. If you pick Iona, download the deck plans before you sail and identify your “triangle” of most‑used spaces: your cabin bank of lifts, your preferred included dining venue and one or two favourite lounges. Build your first two evenings around those. From Day 3, start experimenting with different venues once you are comfortable with the layout. If you expect to order multiple daily drinks, read our Iona drinks package guide 2026 and confirm current package terms with P&O before buying onboard.

      Accessibility and mobility: plan with the deck plans (guidance)

      For guests with mobility or accessibility needs, the most important step is to review P&O’s deck plans for Iona and speak to P&O (or your travel agent) before booking to confirm cabin features, doorway widths, bathroom layouts and proximity to lifts that suit your requirements. On a large ship, travel distances between venues can be longer than expected; choosing a centrally located cabin stack can ease daily routines. Policies and accessible cabin inventories can change, so verify specifics directly with P&O for your 2026 departure.

      Strengths and trade‑offs in plain English (editorial)

      Strengths
      - Huge choice of dining and entertainment (officially, approximately 30 bars/restaurants and 10 entertainment venues).
      - Four pools and the SkyDome provide both outdoor and weather‑proof options.
      - Southampton homeport is convenient for UK travellers and removes flight risk.
      Trade‑offs
      - Peak‑time crowds require a bit of timing and planning.
      - Longer walking distances than on small ships; lift waits can be longer at peak times.
      - If you prefer a quiet, boutique atmosphere, Iona may feel lively compared to smaller vessels.

      What’s included vs extra‑cost on Iona in 2026 (how to think about it)

      P&O’s dining information confirms there is a mix of included dining and speciality venues at extra cost. Beyond dining, large mainstream ships typically include many entertainment options and pool access as part of the fare, with certain extras chargeable. Because inclusions and policies can change, the safest approach is to list the categories that matter to you—dining, drinks, Wi‑Fi, specialty experiences—and ask P&O or your travel agent to confirm what is included for your specific 2026 sailing. If drinks are a focus for you, consult our Iona drinks package guide 2026 and verify current package rules with P&O before deciding whether to buy.

      How to avoid crowds on a very large ship (editorial tactics)

      • Dine slightly off‑peak: earlier breakfasts, later lunches, and pre‑show dinners.
      • If a venue has multiple showings, choose the less popular time slot.
      • Use the ship’s forward or aft lifts that are less central at peak times.
      • On sea days, arrive early to your preferred pool or choose a late‑afternoon swim.
      • Build a simple daily rhythm: one headline activity, one relaxed break, one planned evening anchor.

      Using the SkyDome and Grand Atrium to your advantage

      The SkyDome’s glass canopy creates a reliable daytime retreat regardless of the British weather, with the flexibility to host evening events. The Grand Atrium functions as a central “living room,” ideal for people‑watching and pre‑dinner meet‑ups. Editorially, a smart pattern is to start early evenings with 20–30 minutes in the Atrium, move to a nearby included dining venue, and finish with a show—this triangle minimises cross‑ship walks during the busiest hour and keeps the night flowing.

      Sea days vs port days: pacing your week (editorial)

      On sea days, larger ships concentrate activity onboard, which can make mid‑mornings and early afternoons the busiest windows. To keep things relaxed, consider a pre‑lunch swim or schedule your main show for early evening rather than prime time. On port days, many venues are quieter right after sail‑away—an ideal time to explore new corners of the ship. Whichever rhythm you choose, decide your “must‑do” each day and build around it rather than trying to do everything.

      Budgeting for 2026 without guesswork

      Because prices, packages and promotions can change, the best budgeting method is to separate your spend into two buckets: essentials you will definitely use (for example, a speciality dinner if you are celebrating) and variables you can adjust day‑by‑day (such as extra snacks or premium coffees). Track your actual usage over the first 24 hours, then adjust. If you are considering a drinks package, read our Iona drinks package guide 2026 and confirm the current price and terms with P&O before committing.

      Comparing Iona with other UK cruise options in 2026 (editorial)

      If you want maximum onboard choice, Iona’s scale is a clear draw. If you prize small‑ship intimacy and quieter venues above all else, you may prefer a smaller vessel from lines that cater to that style. For a classic ocean‑liner atmosphere and more formal traditions, some UK travellers look at established British brands. The key is to match ship size and onboard energy to your personality: Iona excels at variety, modern British styling and family‑friendly flexibility from a Southampton homeport.

      Final recommendation: should you book Iona in 2026?

      If your priority is a big choice of places to eat, drink and be entertained without flying, P&O Iona is easy to recommend for families, sociable couples and first‑time cruisers. The weather‑resilient SkyDome and four pools give you flexibility, and the Grand Atrium offers a lively central hub. The necessary trade‑off is managing peak‑time crowds on a very large ship. If you are happy to plan dining and shows, you will unlock the best of what Iona offers. Before you book, confirm the latest details on P&O’s site—especially dining inclusions, deck plans and any package terms—so your 2026 expectations match reality.
