Cruise Packing Don’ts Every Traveler Should Know

How we work: facts are checked against original sources and linked, cruise prices are verified on the cruise line’s own website the day we publish, and we earn no commissions. Spotted a mistake? Tell us and we will correct it. Last updated September 25, 2026.

Every cruise terminal has a moment the brochures leave out. Your bag goes through the scanner, a security officer lifts the lid, and something you packed without a second thought comes out and does not go back in. It is almost never the thing people expect. It is an iron, a power strip, a candle, or a bottle of rum in a shampoo bottle that fooled nobody.

What makes this worth understanding properly is that the four biggest lines do not just ban different things. They do different things with the item afterwards — and that difference is worth real money. One line disposes of it and owes you nothing. One hands it back on the last night. One holds it and gives you fifteen days to collect it before it is gone for good. Almost no packing guide mentions this, because almost no packing guide reads the policies.

Here is what actually gets taken at the gangway, why, and what happens to it next — every rule below quoted from the cruise line’s own published page.

The iron is the single most confiscated item

If you take one thing from this article: do not pack a clothes iron or a garment steamer. Every major line bans them, and they are the item passengers are most surprised to lose.

Carnival’s prohibited items list names “Clothing irons, Garment steamers” under Electrical and Heating Devices. Royal Caribbean states plainly that clothing irons and garment steamers are prohibited. Princess files them under heating elements, banning “items containing any kind of heating element, such as but not limited to: immersion heaters, heating blankets, clothing (garment) irons, water heaters, coffee machines with heating / hot plates, etc.”

The reason is the one thing a ship genuinely fears. A fire at sea has nowhere to go and no fire brigade to call, so anything that turns electricity into concentrated heat and can be left face-down on a bedspread is treated as a serious risk. That is also why the ban survives the obvious objection — yes, the ship has irons. Norwegian keeps a limited number of irons and ironing boards that housekeeping will lend you for a few hours, and most lines run a self-service laundry with fixed, supervised equipment. The rule is not “no ironing”. It is “no ironing unsupervised in a cabin”.

Personal grooming heat is treated differently, and this is where people get caught by the detail. Norwegian allows “hair dryers, hair flat irons, curling irons and shavers… when used with proper caution” — but adds that “if such devices are determined to pose a hazard while onboard, they will be removed by ship security and returned the last day of the cruise prior to debark.” A curling iron is fine until a crew member decides yours is not.

The power strip problem

Modern cabins have famously few sockets and passengers arrive with more devices every year, so the power strip has become the second great confiscation story. The rule turns on one word: surge.

Princess bans “electrical devices with surge protectors such as small fans, multi plug box outlets/adaptors, power strips/extension cords”, while noting that equivalent devices without surge protection may be permitted after inspection by the onboard electrical department. Carnival takes the same line from the other direction, permitting “extension cords without surge protection”. Royal Caribbean groups extension cords, power strips and multi-plug outlets together as electrical items requiring review or special handling.

So the practical rule is simple, and it is the opposite of what most people assume: on a ship, the protected version is the banned one. A plain, unprotected multi-plug or a USB charging block is the thing to pack. The engineering reason involves how shipboard electrical distribution differs from the wiring in your house, and it deserves its own article rather than a paragraph here — we will link that one from this page when it runs.

What happens to it afterwards — and why the line matters

This is the part no packing checklist covers. Losing an item at the gangway is an inconvenience; losing it permanently is a cost. The four big lines resolve that question in four genuinely different ways, in their own published words.

Cruise line	What its own policy says happens to a confiscated item
Carnival	“Confiscated items will be removed and disposed without compensation.” Drones are the named exception — declared at embarkation and held by the Chief Security Officer.
Royal Caribbean	Asterisked categories “may be retained by Security for the duration of the cruise and returned to the guest upon departure”. But the Guest Health, Safety and Conduct Policy adds a deadline in capitals (see below).
Norwegian	Grooming devices judged hazardous “will be removed by ship security and returned the last day of the cruise prior to debark”.
Princess	“Prohibited items will not be allowed or stored on board the vessel with no exceptions.” Guests are responsible for storing or disposing of them before embarkation.

Read that table again with a $90 steamer in mind. On Norwegian it comes home with you. On Carnival it is gone, and the policy says so without hedging. On Princess it never gets aboard at all, which means the decision lands on you in the terminal car park with a ship to catch.

The fifteen-day clause

Royal Caribbean looks like the most generous of the four until you read its Guest Health, Safety and Conduct Policy, where the prohibited items clause carries this sentence in full capitals:

“CONFISCATED ITEMS NOT CLAIMED BY GUESTS WITHIN 15 CALENDAR DAYS OF CONFISCATION SHALL BE DEEMED FORFEITED AND MAY BE DISPOSED OF BY ROYAL CARIBBEAN GROUP.”

Fifteen days runs from confiscation, not from disembarkation. On a long voyage, an item taken in week one can be close to its deadline by the time you walk off. If something of yours is held, get a written note of what was taken and when, and ask Guest Services exactly where and how it will be returned before you leave the ship.

The rest of the banned list, briefly

Beyond heat and electricity, the lists converge. Carnival’s covers illegal drugs and controlled substances including CBD products; weapons from firearms to brass knuckles, stun guns and tasers; explosives and flammables such as fireworks, gasoline and paint thinners; and compressed gases including propane and dive tanks, with aerosol grooming products specifically allowed. Candles and incense appear on every list — Norwegian names “candles and incense burners” outright.

One modern addition catches people out: portable speakers. Carnival bans “boom boxes, Bluetooth speakers, portable speakers”, with the reasoning stated directly — “Guests must use earphones or headphones when listening to music or watching videos in public areas.”

Three categories we have covered in depth separately, because each has enough exceptions to need its own page: alcohol (Carnival allows one 750ml bottle of wine or champagne per adult; the rules differ sharply by line), food and snacks, and satellite internet equipment.

The other packing mistake: things nobody confiscates

Security will not take your seventh pair of shoes. A cruise cabin will simply defeat them. Cabin storage is built around the fact that you unpack once, so the constraint is not weight allowance but drawer space and the wardrobe you are sharing.

The items most often regretted are the ones bought specifically for the trip and worn once: formal shoes for a single dinner, a second formal outfit, beach towels the ship already provides, and a hairdryer that duplicates the one fitted in the cabin. The items most often missing are duller — a plain extension block without surge protection, a lanyard, motion sickness tablets bought ashore at ashore prices, and a change of clothes in your hand luggage for the hours between boarding and your checked bag arriving at the cabin door.

What to do before you pack

• Leave the iron and the steamer at home. Every major line bans them. Use the ship’s laundry or borrow one from housekeeping.
• Check the word “surge” on any power adapter. Unprotected is permitted; surge-protected is the banned version. Princess will have its electrical department inspect the unprotected sort.
• Read your own line’s list, not a generic one. These policies differ in exactly the places that cost money, and they change — always open the line’s own page for the sailing you have booked.
• If something is taken, get it in writing. Note what was taken and the date. On Royal Caribbean that date starts a fifteen-day clock.
• Assume a confiscated item is gone unless the policy says otherwise. Only Norwegian’s wording promises a return as a matter of course; Carnival’s promises the opposite.

Quick Answers

Can you bring an iron on a cruise?

No. Carnival, Royal Caribbean and Princess all name clothing irons and garment steamers as prohibited, because of fire risk in an unsupervised cabin. Norwegian lends irons and ironing boards through housekeeping instead, and most ships have a self-service laundry.

Are power strips allowed on cruise ships?

Only without surge protection. Carnival permits “extension cords without surge protection”; Princess bans the surge-protected kind but will allow unprotected devices after inspection by the ship’s electrical department. The surge-protected version is the one that gets taken.

Do you get confiscated items back at the end of a cruise?

It depends entirely on the line. Norwegian returns hazardous grooming devices “the last day of the cruise prior to debark”. Royal Caribbean may retain asterisked items and return them on departure, but unclaimed items are forfeited after 15 calendar days. Carnival states confiscated items “will be removed and disposed without compensation”.

Can you bring candles on a cruise?

No. Candles and incense are prohibited across the major lines — Carnival lists “Candles, Incense, Hookahs” under open flame and smoking accessories, and Norwegian names “candles and incense burners” on its prohibited list.

Can you bring a Bluetooth speaker on a cruise?

Not on Carnival, which prohibits “boom boxes, Bluetooth speakers, portable speakers” and requires headphones for music or video in public areas. Other lines vary, so check the line’s own list before packing one.
