Embarkation day on P&O Iona is very different to what many people expect, especially if this is your first cruise. This is one of the largest ships sailing from the UK, carrying more than six thousand passengers, and that scale changes how the entire boarding process works.
On paper, embarkation looks simple. You arrive at the terminal, check in, and walk onboard. In reality, there are queues, timing restrictions, and a few parts of the process that can catch people out if you are not prepared.
I’ve boarded Iona myself twice from Southampton, and the biggest difference compared to other cruise lines is not the process itself, but how compressed everything feels. A lot of people are arriving within a short window, and that creates pressure points at certain stages of the day.
This guide breaks down exactly what to expect, from before you arrive at the terminal through to your first evening onboard.
Watch: Iona Embarkation Day – What to Expect
See exactly how embarkation works on Iona, including queues, check in, and what to do once you board.
1. What do you need to do before embarkation day on Iona?
Preparation before you arrive in Southampton makes a noticeable difference to how smooth your embarkation feels.
Online check in normally opens around 21 days before your sailing. This is where you upload passport details, add a payment card, upload a photo, and download your boarding pass and luggage tags. If you leave this incomplete, you will slow yourself down at the terminal.
Your embarkation time is also assigned during this stage. On P&O Cruises, you cannot choose your boarding time. It is allocated based on your cabin location and loyalty tier. Guests in higher Peninsular Club levels or suites are usually given earlier slots, while most passengers are assigned later times in the afternoon.
Show reservations in the Headliners Theatre also normally open around 14 days before departure. There are usually three performances each evening, and the middle show at 8:30pm is the most popular. Booking that early avoids having to adjust your plans later in the week or risk missing out on a show you really want to see.
If you are travelling with children, pre registering for The Reef is worth doing in advance. It does not take long, but it removes one more queue on embarkation day.
This is also the point where you want to have your documents ready in one place. Printed boarding passes are still required at Southampton, and that catches some people out.
2. Where do you park and arrive for Iona in Southampton?
Most passengers sailing on Iona arrive at the port by car, and the process is generally straightforward.
P&O Cruises use CPS parking at the terminal. You drive directly into the drop off area, hand your keys to staff, and your car is parked for you during the cruise. When you return, it is brought back to the terminal for collection, even if the ship docks somewhere different.
The important detail here is timing. If you arrive too early, you will still be asked to wait. If you arrive too late, you risk joining a longer queue than necessary.
Some passengers choose to arrive by train or taxi instead. Southampton Central station is a short taxi ride from the terminals, and this avoids the need to book parking in advance.
3. Why does embarkation on Iona feel chaotic?
This is one of the most common concerns, and it comes down to scale and timing. Iona carries more than six thousand passengers, and embarkation times are grouped quite tightly in the afternoon. That means a large number of people arrive at the same time, even if they all technically have different slots.
On my sailing, there was already a queue outside the terminal when we arrived at our allocated time. It took around an hour before we even entered the building.
The key point is that arriving earlier does not necessarily help. Embarkation times are usually checked, and you may simply be asked to wait outside until your group is called.
Compared to cruise lines where you select your own arrival window, the process on Iona feels more chaotic. That is why the early part of the day can feel disorganised, even though the system itself is working as intended.
4. What actually happens inside the terminal?
Once your group is called, things move much more smoothly. You enter the terminal, join the check in desks, and present your passport and boarding pass. Your boarding pass is stamped at this stage, confirming that you are cleared to board.
After check in, you either move straight to security or are asked to sit briefly until your row is called forward. Security is similar to an airport process, with bags scanned before you continue.
From there, you walk directly onto the ship via the gangway. This part of the process is usually quick. Most of the waiting time happens before you enter the building, not inside it.
5. What should you do first when you board Iona?
The first thing you will be directed to do is visit your muster station. On Iona, this is a quick check in process where crew scan your card and confirm your attendance. You then watch the safety video later in your cabin.
Cabins are normally ready when you board, which is one of the advantages of the later embarkation times. Your cruise card will usually be waiting outside your door, so you can go straight to your cabin and drop your bags.
This is also the moment to connect to the My Holiday system onboard. Some restaurants and venues only open bookings once you are connected to the ship’s network.
On my sailing, by the time we boarded after the queues, several popular venues were already fully booked for the week. That does not mean you cannot get in later, but it does mean you should check availability early.
6. Where can you eat on embarkation day on Iona?
Food is one of the first decisions people make once they board, and this is where the ship can feel busy. The Horizon buffet is the most obvious option, and it is usually very crowded on embarkation day.
There are alternatives that are often easier. The Quays and Taste 360 tend to be less busy early in the day, and they are a better option if you want to avoid queues.
Some passengers also have access to a welcome lunch in the main dining room depending on their loyalty level, which is a more relaxed way to start the cruise.
The key point is to avoid heading straight to the buffet without considering other options, especially if you board during the busiest period.
7. How do you find your way around Iona on day one?
Iona is a large ship, and the first afternoon is the best time to get familiar with it. Deck plans are located near the lifts, and spending an hour walking the ship early on saves time for the rest of the cruise.
One thing you will notice quickly is how busy the lifts are. Thousands of passengers are moving around at the same time, many with hand luggage, and this creates delays. For shorter distances, the stairs are often quicker.
If you want a full walkthrough of the ship layout, including how the decks connect and where everything is located, my What’s Onboard Iona guide explains this in detail.
8. When does luggage arrive and what happens at sailaway?
Suitcases are usually delivered outside your cabin during the afternoon, often between four and five o’clock. This gives you time to unpack before dinner and settle into the cabin properly.
Sailaway is another key moment on embarkation day. In good weather, passengers gather on the open decks as the ship leaves Southampton. If conditions are colder or windy, the focus shifts to indoor areas like the SkyDome.
There are quieter options if you want to avoid the crowds. Some areas of the ship are still relatively empty on the first day, particularly around the outer decks.
9. How does dinner work on the first night?
Dinner on Iona operates differently to traditional fixed dining. At around six o’clock, virtual queues open in the My Holiday App system. You choose a main dining room and join the queue through the app.
Waiting times vary, but around thirty minutes is common. You do’ot need to stand outside the restaurant. You are notified when your table is ready, which allows you to wait elsewhere on the ship.
This system works well once you understand it, but it can feel unfamiliar on the first evening if you are expecting a set dining time.
10. What does the first evening on Iona feel like?
The tone of the day changes quickly once the ship leaves port. Embarkation can feel slow and slightly stressful at the start, particularly with queues and timing. By the evening, the atmosphere is completely different.
You have unpacked, found your way around, and started to settle into the rhythm of the ship. If this is your first cruise, it is easy to feel unsure during the early part of the day. Once you reach the first evening, everything becomes much clearer.
