Can you cruise with only a carry-on? What four cruise lines say
Of the four cruise lines we read, only Royal Caribbean says outright that "Each guest has the option to carry their luggage on board", and it warns that your stateroom "may not be immediately available". Our pick is one bag that fits your flight's cabin limit, carried aboard, with documents, medications and a swimsuit on top. The trade-off is hauling it around until the cabin opens. Carnival, Norwegian and Princess don't say either way on their pages, so ask the line first.
Can you carry all your luggage aboard yourself?
We read the luggage pages of Royal Caribbean, Carnival, Norwegian (NCL) and Princess. Each cell below gives that line's own words, and "not stated" means we found nothing on the subject on its pages.
| Rule | Royal Caribbean | Carnival | Norwegian (NCL) | Princess |
|---|---|---|---|---|
| Carrying your own luggage aboard | "Each guest has the option to carry their luggage on board or check-in luggage prior to boarding." Also: "Guests wishing to carry their luggage with them during boarding should note that their stateroom may not be immediately available to store their luggage." (read 18 Oct 2026) | Not stated (read 18 Oct 2026) | Not stated (read 18 Oct 2026) | Not stated (read 18 Oct 2026) |
| Size of a bag you hand-carry | "Any carry-on luggage must be able to fit through the x-ray screening machines." The machines "vary in size from port to port". (read 18 Oct 2026) | "Each checked or carry-on suitcase should not exceed 50 pounds. When lying flat, bags must not exceed 16 inches high by 24 inches wide; the length of the bag is not a factor." (read 18 Oct 2026) | "Luggage that is being hand-carried must be able to fit thru the x-ray machines, similar to airplanes if larger than that it must be checked. (Approximately 24” tall and 18” wide)" (read 18 Oct 2026) | "There are typically no formal size or weight restrictions enforced by the cruise line itself, but large or excessive luggage may be more difficult to store in your stateroom." (read 18 Oct 2026) |
| How many bags | "Each guest is permitted to carry a reasonable amount of personal property (including luggage) aboard the vessel; however, for your comfort and convenience, it is recommended that you limit the number of pieces you take." (read 18 Oct 2026) | "we suggest you limit your luggage to a maximum of one bag per person, if traveling on cruises of 3-5 days duration, and no more than two bags per person, for cruises of 6 days or longer." (read 18 Oct 2026) | Not stated (read 18 Oct 2026) | Pack "a reasonable amount that you can comfortably manage" (read 18 Oct 2026) |
| Locks | "Luggage may be locked only with a TSA approved lock." (read 18 Oct 2026) | Asks that all luggage be left without locks "for security screening" (read 18 Oct 2026) | Not stated (read 18 Oct 2026) | Not stated (read 18 Oct 2026) |
| Bag types | Not stated (read 18 Oct 2026) | "Hulken rolling totes, wagon-style bags, and other similar totes are prohibited onboard." (read 18 Oct 2026) | Not stated (read 18 Oct 2026) | Not stated (read 18 Oct 2026) |
For a carry-on-only trip, Royal Caribbean is the one line of the four that says yes in writing. Carnival's page describes its porter service instead. Checked baggage service stops 2 hours before the published departure time, and "Guests arriving after this time will be responsible for taking their bags on board." Norwegian and Princess don't address it. On those three lines, check with the line before you skip the porter. Carnival's size rule covers "Each checked or carry-on suitcase", so it isn't a limit for carry-on-only travellers alone.
Banned items that change a one-bag cruise
A bag that holds the whole trip also goes through each line's banned-items list. These are the entries that change what one bag can hold.
| Item | Royal Caribbean | Carnival | Norwegian (NCL) | Princess |
|---|---|---|---|---|
| Clothes irons | "Clothing irons and garment steamers are prohibited." (read 18 Oct 2026) | "Clothing irons" and "Garment steamers" are on its list of electrical and heating devices not allowed (read 18 Oct 2026) | Items "containing any kind of heating element, such as but not limited to: immersion heaters, heating blankets, clothing irons" (read 18 Oct 2026) | Items with a heating element, "such as but not limited to: immersion heaters, heating blankets, clothing (garment) irons" (read 18 Oct 2026) |
| Hair tools | "Personal hair appliances like curling and flat irons are permitted for personal use. However hair dryers may be prohibited onboard depending on their specifications, and you will find one in your stateroom." (read 18 Oct 2026) | "Hair dryers", "Curling irons" and "Flat irons" are on its list of items generally permitted (read 18 Oct 2026) | "Personal grooming devices such as hair dryers, hair flat irons, curling irons and shavers are allowed on board when used with proper caution." (read 18 Oct 2026) | Not stated (read 18 Oct 2026) |
| Power strips | "extension cords, power strips" are among the electrical items its page says "are prohibited" (a fragment of a longer list; read 18 Oct 2026) | "Power strips" are on its list of items generally permitted, with the note "These items may be removed if deemed unsafe." (read 18 Oct 2026) | Not stated (read 18 Oct 2026) | The page says two different things, quoted below the table (read 18 Oct 2026) |
All four lines we read ban clothing irons. On power strips, Princess's own page contradicts itself. Its prohibited list includes "Electrical devices with surge protectors such as small fans, multi plug box outlets/adaptors, power strips/extension cords." Its electronics tips say: "Bringing a non-surge protected power strip or USB hub can be helpful for keeping everything powered. For safety reasons, extension cords and surge-protected power strips are generally not permitted onboard." Ask Princess before packing one.
Carnival adds two carry-on rules of its own: "Power banks, portable chargers, and e-cigarettes must be carried onboard in carry-on luggage only", and for CPAP machines, "Must be carried on board as carry-on luggage". The flight rules for the same items are on the electronics guide and the CPAP guide. The flight to the port follows your airline's limits, listed in carry-on limits by airline and personal item size by airline.
What goes in your embarkation-day bag
If you do hand your main bag to a porter, the bag you keep matters until the checked one is delivered to your cabin. Princess says "Checked luggage is typically delivered to your cabin within a few hours after boarding, often by early evening." Each line lists what to keep with you, in its own words (all read 18 Oct 2026):
- Royal Caribbean: "It is also a good idea for guests to pack a small carry-on bag with a change of clothes, and bathing suit." It also recommends that guests "personally carry any boarding documentation such as passports, visas, citizenship documents and family legal documents plus all medications."
- Carnival: "boarding documentation (passports, Visas, I.D), valuables, medications and items which require special handling."
- Norwegian: "We recommend that guests hand-carry medication, jewelry, breakables, or other valuables, an extra set of clothes for the first evening on board, and important documents".
- Princess: "We recommend bringing your travel documents (such as your passport and boarding information), medications, valuables and electronics."
Our list below uses only items at least one of those lines names, plus a phone charger and a light layer.
Embarkation-day bag (our list)
The last night: bags go out before you leave
Royal Caribbean's packing page says "Bring an overnight bag for your last night at sea. Staff will collect your luggage the night before disembarkation". Norwegian says "Guests should bring a spare overnight bag because all suitcases are collected the night before we return to homeport." Carnival and Princess don't mention it on the pages we read. On Royal Caribbean, where carrying your own bag is stated, our reading is that a carry-on-only traveller keeps the one bag through the last night. On the other three, ask the line.
Medication on board
Royal Caribbean says "we advise that all medications remain in their original, labeled prescription containers" and "It is also advisable to pack at least three days of extra medication in the event of an unexpected change in the itinerary of the voyage." Norwegian recommends that guests "hand-carry medication". Princess says "medications should be kept in their original labeled containers and packed in your carry-on luggage." Carnival lists medications among the items you "must personally carry-on". For medical equipment, Princess adds that "you will be expected to carry all your own equipment and supplies." Screening the same medicine at the airport is on carry-on medication rules.
Worked example: a week on Royal Caribbean with one bag
Our plan, using Royal Caribbean because it's the only one of the four lines that states you can carry your own luggage aboard:
- Flight to the port. The bag has to meet the airline's cabin limit, so check your airline's row in carry-on limits by airline before packing.
- Boarding. The bag goes through the terminal x-ray, which Royal Caribbean says it "must be able to fit through". The stateroom "may not be immediately available", so documents, medications and the swimsuit go in an outer pocket for the first afternoon.
- On board. No iron or steamer in the bag, and no power strip. The cabin has a hair dryer, per Royal Caribbean's page, so yours can stay home.
- Evenings. Royal Caribbean's dress-code page prints both "There can be 1-3 Dress Your Best during a sailing" and "There can be 1 to 4 Dress Your Best during a sailing", and says the number "can vary by itinerary". Our plan is one dressier outfit, worn on each of those nights.
- Last night. Royal Caribbean's staff collect luggage the night before disembarkation; our plan keeps the one bag with you.
