Don’t assume that cruise cabins are just hotel rooms at sea!

They might look that way at first glance – but there are loads of little quirks that can catch you out if you’re not prepared.

Cruise cabin secrets

From hidden storage to slightly odd bathroom setups, here are some cruise cabin secrets that’ll make your trip smoother (and a lot more comfortable).

1. There Usually Aren’t Enough Plug Sockets

If you’re travelling with phones, tablets, cameras and maybe a hair tool or two, you’ll quickly notice the lack of plug sockets. Modern ships are a little better, but there are still limitations – and on older ships, expect just a small number of outlets.

Most cabins have a mix of US and European outlets – UK plugs are rare, but it depends on the ship. A simple EU adapter and a USB hub (non-surge protected) will make life much easier, although you need to check what’s permitted on your cruise line, as the rules can vary.

One rule that you should always follow – avoid bringing anything with surge protection, as those are typically banned for safety reasons. Cruise ship wiring doesn’t like surge protected adapters.

2. Cruise Cabin Temperature Can Be Hit or Miss

Some people find cabins freezing, others say they’re too warm – it really depends on the ship and even the exact room.

Air con is centrally controlled, so while you can usually adjust it slightly, you won’t get full control. If you like it cool, you might struggle. If you feel the cold, it can get a bit chilly at night.

Make sure you get used to the air con controls and find a setting that works for you early. And if you’re finding that the room is too cold, ask your cabin steward if they can help – they can often rustle up some blankets.

Rooms being too warm is a trickier issue – fan availability on ships is limited. A lot of cruisers bring their own small ones.

3. Cabin Location Matters More Than You Think

Not all cabins are created equal – and location can make a big difference to your experience.

Cabins near lifts are convenient but can be noisy. Staying under the buffet or directly under the pool deck? Expect early morning scraping chairs. Forward cabins can feel more movement, while aft cabins sometimes have vibration.

Noise on a cruise

Midship cabins on lower decks are usually the most stable if you’re worried about seasickness.

It’s worth checking deck plans before you book – it can save you a lot of hassle later.

4. Cruise Toilets Are Vacuum Powered

Cruise ship toilets aren’t like the ones on land – they use a vacuum system, a bit like on aeroplanes.

They’re powerful, a bit noisy, and very sensitive. You should only flush toilet paper, and even then only the thin paper provided by the cruise line – anything else can cause blockages, which isn’t something you want to deal with mid-cruise.

Another section of a split bathroom on a Disney cruise ship, focusing on the toilet area. The design includes a modern, oval-shaped toilet and a rectangular sink housed in a dark wood vanity with storage underneath. Above the sink is a large mirror with integrated lighting, which adds a bright and spacious feel to the compact area. The walls are painted in a soft gray tone, and the floor is tiled in a gray herringbone pattern, maintaining a consistent style with the previous bathroom section.

Especially as a blockage won’t just affect your cabin, but usually at least a few on your deck, or worse.

That first flush can be a bit of a shock, but you’ll get used to it quickly! Just make sure you’re careful with what you put in there.

5. Storage Is Clever (But Not Always Obvious)

Cruise cabins are designed to maximise space, and there’s often more storage than you first realise.

Look for hidden shelves, drawers under sofas, and cupboards tucked behind mirrors. Under-bed storage is especially useful – perfect for suitcases or bulky items.

Cruise Wardrobe

A good tip is to keep less-used items packed away and rotate things as needed, rather than trying to unpack everything at once.

6. Your Cabin Key Card Controls the Power

This one will either catch you off guard, or you’ll find it completely normal – depending on how often you travel and stay in chain hotels.

P&O Cruise Card

Most cruise cabins have a slot by the door where you insert your key card to activate the electricity. No card = no lights, no sockets, no air con. It can be a bit confusing if you’re new to it!

It’s designed to save energy, but it can be a bit annoying if you want to charge devices while you’re out. Many cruisers use an old loyalty card or spare card to keep the power running. Not exactly encouraged… but very common.

7. Your Cabin Walls Are Magnetic (But the Bathroom Isn’t)

Here’s a handy little trick – most cabin walls are made of metal, so magnets will stick to them.

Magnetic hooks are brilliant for hanging jackets, bags or even organising paperwork like daily schedules and excursion tickets.

Just don’t expect them to work in the bathroom. Shower walls are usually tile or fibreglass, so you’ll need suction hooks there instead. Though there’s usually enough bathroom space to store your essential toiletries anyway.

8. Cruise Ship Bathrooms Don’t Always Have Ventilation

Not every cabin bathroom comes with an extractor fan – which can be… interesting if you’re sharing a small space. Even those that do have a fan might not have a very powerful one.

A simple fix is to bring a light room spray or hanging freshener. Nothing too strong, just enough to keep things fresh.

Candles and anything with an open flame are strictly banned, so stick to sprays or oils (and check cruise line rules before bringing diffusers).

9. Beds Can Be Rearranged (But Not Much Else)

Cruise cabin beds are surprisingly flexible. They’re usually set up as two singles that can be pushed together to make a double.

If it’s not how you expected when you arrive, just ask your cabin steward – they’ll sort it quickly. Don’t do it yourself, it’s best to let them do it as they can make sure it’s done properly.

Beyond that, though, don’t expect to move much else. Most furniture is fixed or weighted to stop it sliding around at sea.

10. Leaving the Balcony Door Open Can Cause Chaos

It’s tempting to let in some fresh sea air, but opening your balcony door while your cabin door is also open creates a wind tunnel.

Paperwork goes flying, doors slam, and it can be surprisingly forceful.

If you want fresh air, just keep one door closed – and maybe keep loose items tucked away just in case.

And never leave your cabin with the balcony door left open – you might have a hard time getting back into the cabin due to the wind!

11. Tap Water Is Safe to Drink

There’s often confusion about this, but yes – cruise ship tap water is perfectly safe.

It’s filtered and treated to high standards, and it’s the same water used in restaurants and bars across the ship.

The only downside to the tap water is that it might not be very cold. You’ll get ‘cold’ water, but really it’s tepid.

Bringing a reusable water bottle is a great idea – it saves money and cuts down on plastic. But you’ll usually get colder water from the dispensers around the ship.

12. Some Cabins Have Hidden Perks

Not all “standard” cabins are equal. Some have surprisingly good features without costing extra.

Corner aft cabins often have larger balconies, while some forward-facing rooms offer huge windows and unique views.

The image shows a deck plan for a section of the Sun Princess. The plan includes various staterooms, color-coded to indicate different categories or types of cabins. The layout is symmetrical, with staterooms lining both sides of a central corridor. The central area includes stairs and elevators, as well as what appears to be laundromat facilities (labeled "Laundromat"). The plan highlights specific corner staterooms with red arrows, possibly indicating rooms with unique features, such as larger layouts or enhanced views. The color coding and arrows help in identifying key areas and special rooms on this deck.

Even just the design of the ship can result in a slightly larger balcony – something you might not need to pay extra for.

It’s worth doing a bit of research before booking – you might be able to snag a much better cabin for the same price. Deck plans are super valuable for this.

13. Inside Cabins Can Still Feel Connected to the Outside

Worried about feeling boxed in with no window if you book an Inside cabin?

Inside cabin with TV

Many ships have a live bridge cam channel on the TV, showing real-time views from the front of the ship. It’s a simple trick, but it helps you stay connected to the outside world.

Some people even leave it on overnight for a gentle “sunrise” wake-up.

Being honest, don’t expect an incredible Ultra-HD view – but it’s a handy way to see how light (or not) it is outside.

14. You Can Ask Your Cabin Steward for More Than You Think

Your cabin steward can make a big difference to your stay – and you can ask for quite a lot.

Extra hangers, mattress toppers, more pillows, ice deliveries, even clearing out the minibar fridge so you can use it yourself.

They’re there to help, so don’t be shy about asking. If they can’t fulfil a request, they’ll let you know, but they won’t admonish you.

Just try not to be ridiculous with your requests. Remember how busy they are.

15. Kettles Aren’t Standard on Most Cruise Lines

This one is for my UK readers. If you’re used to a cuppa whenever you fancy it, this one can catch you out.

Cruise ship kettle

Most cruise cabins don’t come with kettles, especially on international cruise lines. You’ll usually need to head to the buffet or order room service for tea and coffee.

Some UK-focused lines like Marella Cruises, P&O Cruises and Cunard do include kettles – but it’s always worth checking before you sail.

Final Word

Cruise cabins are clever little spaces – but they definitely don’t behave like your average hotel room. Once you understand the quirks, from power slots and plug sockets to vacuum toilets and hidden storage, everything just becomes easier.

A bit of planning goes a long way, and knowing what to expect means fewer surprises (and fewer annoyances) once you’re onboard.

Get these basics right, and your cabin becomes exactly what it should be – a comfortable, stress-free base for your cruise holiday.
