What can’t you bring on a cruise? The items most often confiscated at cruise security are extra alcohol, surge protectors, clothes irons and steamers, candles, marijuana and CBD products, weapons (including pocket knives and toy guns), drones, and personal Wi-Fi gear such as Starlink dishes and travel routers. Most of these are held until the last day of the cruise, while drugs and opened alcohol are usually discarded.

The good news is that almost everything on the banned list has a cruise-friendly alternative. Below are the 14 items that most often get pulled from bags at the terminal, a line-by-line alcohol table for 2026, and what to pack instead so your luggage reaches your cabin without a call from security.
Cruise prohibited items: the quick version
Every cruise line publishes its own prohibited items list, and they differ in the details. A few rules are close to universal, though:
- No weapons, ammunition, fireworks or replicas of weapons.
- No illegal drugs, and that includes marijuana and CBD even when they are legal where you live or you hold a medical card.
- No open-flame or heat-producing items such as candles, incense, irons and hot plates.
- No extension cords or power strips with surge protection.
- Strict limits on what you can drink from home, usually wine only.
Security staff also have discretion. Royal Caribbean, for example, says items not on its list can still be refused if they are judged unsafe, with the final call resting with the ship’s senior officers. When in doubt, check your line’s official page before you pack.
The 14 most commonly confiscated items at cruise ports
1. Extra wine, beer and spirits
Alcohol is the number one item pulled at security. Most lines allow one 750 ml bottle of wine or Champagne per adult on embarkation day and nothing else. Beer, hard seltzer and liquor are banned on almost every mainstream line, and staff know the tricks: rum in mouthwash bottles and vodka in water bottles get spotted on the scanners. Pack instead: your single permitted bottle in your carry-on, or look at the cruise drink package loopholes that still work in 2026 if you want to drink more for less.
2. Bottled water and soda
Soft drink rules vary more than people expect. Royal Caribbean allows up to 12 standard (17 oz) cans, bottles or cartons per stateroom on boarding day. Carnival allows 12 cans or cartons of up to 12 oz per person but not plastic or glass bottles. Norwegian and MSC don’t allow guests to bring water or soda at all, apart from sealed water needed for infant formula or medical devices. Pack instead: a refillable water bottle, which you can fill for free at the buffet, or cans and cartons where your line permits them.
3. Surge protectors and surge-protected power strips
Surge protectors are banned because they can interfere with a ship’s electrical system and create a fire risk. Royal Caribbean goes further and bans extension cords, power strips and multi-plug outlets in general. Carnival allows extension cords and power strips without surge protection when used safely. Pack instead: a compact non-surge USB charging cube or a power strip clearly labeled “no surge protection” (often sold as “cruise-approved”), but only if your line permits strips at all. Many newer cabins already have USB ports by the bed.
4. Clothes irons and garment steamers
Irons and steamers are near the top of the confiscated list because they get very hot and are easily left on. Royal Caribbean prohibits both outright, and Carnival returns them at the end of the cruise. Pack instead: wrinkle-release spray, wrinkle-resistant fabrics, or the ship’s pressing service. Hanging clothes in the bathroom during a hot shower also helps.
5. Candles, incense and wax warmers
Open flames are a serious hazard at sea, so candles and incense are banned everywhere, including those that are “just for decoration”. Pack instead: battery-operated LED candles or a small LED string light for a birthday or anniversary setup.
6. Marijuana and CBD products
Cruise ships follow federal and international law, not state law. Royal Caribbean bans marijuana “regardless of medical authorization or local legality”, and Carnival lists CBD items by name. Ports often use detection dogs, and possession can bring trouble with local authorities, not just the cruise line. Pack instead: leave it at home. Bring prescription medication in its original labeled packaging in your carry-on.
7. Starlink dishes, satellite gear and travel routers
This is the newest addition to many banned lists. Carnival bans satellite dishes and routers, and in late 2024 Royal Caribbean added “satellite dishes, routers, and other networking equipment” to its list. Passengers who brought a Starlink Mini aboard have had it confiscated. Pack instead: buy the ship’s Wi-Fi package before sailing (it is usually cheaper pre-cruise) and download shows and maps at home.
8. Drones
Drones are banned outright on many lines because of privacy and navigation concerns. Where they are accepted, for example under Carnival’s rules as reported in 2024, security holds them and you can only use them in port, subject to local laws. Pack instead: a phone gimbal or action camera, which are generally fine.
9. Knives, scissors and tools
Pocket knives, multi-tools and large scissors are frequently pulled. Royal Caribbean allows scissors with blades under four inches, while Princess and Holland America ban many hand and power tools. Some knives and tools are held by security and returned at the end of the cruise. Pack instead: small blunt scissors in your toiletry kit and a TSA-style multi-tool with no blade.
10. Weapons, replicas and self-defense items
Firearms, ammunition, fireworks and sparklers are banned without exception, even if you have a carry permit. Toy guns, replica weapons and many self-defense items are also refused. Pack instead: nothing. If kids want a costume prop for a theme night, choose something that clearly isn’t a weapon.
11. Heating appliances: kettles, coffee makers and hot plates
Anything that heats food or water is treated as a fire hazard, as are electric blankets and heating pads. Pack instead: use the buffet and coffee bars, which run long hours, or ask your cabin steward about tea service.
Cruise banned items that catch people out
12. Fans and small appliances
Cabins can feel warm, so many people pack a fan. Carnival allows fans under 12 inches in diameter, while lines with stricter electrical rules may refuse plug-in models. Pack instead: a small battery or USB-powered clip fan, which avoids most electrical rules.
13. Bluetooth speakers
Speakers and radios appear on several lines’ banned or restricted lists because of noise complaints, and they are typically held and returned at the end of the sailing. Pack instead: headphones, plus a few fun games to bring on a cruise for cabin or deck downtime.
14. Door decorations and hanging decor
Decor rules have tightened. Norwegian has long banned door decorations, and since June 2026 Disney limits decorations to the stateroom door itself, not hallway walls or ceilings. Carnival bans curtains and hanging room dividers. Fresh flowers and plants are also refused on many lines. Pack instead: magnets or removable decorations that stay on the door, and order flowers through the cruise line’s gift service. Families should check the rules first, especially on the best cruise lines for families with kids, where door decorating is a popular tradition.
Cruise alcohol rules by line (2026)
Here is how the major US lines compare for bringing your own alcohol as of November 2026. Fees and limits change, so confirm on your line’s site before you sail.
| Cruise line | Wine you can bring | Corkage fee | Water and soda |
|---|---|---|---|
| Royal Caribbean | One sealed 750 ml bottle per adult; no beer or spirits | Charged in public venues (around $15); none in cabin | Up to 12 cans, bottles or cartons (17 oz) per stateroom |
| Carnival | One 750 ml bottle of wine or Champagne per adult | Around $15 in dining rooms and bars; none in cabin | 12 cans or cartons (12 oz) per person; no plastic bottles |
| Norwegian (NCL) | Sealed wine or Champagne only; no limit stated | $15 per 750 ml, $30 per 1.5 L, even in your cabin; waived with a beverage package | Not allowed |
| MSC | None allowed | N/A | Not allowed |
| Celebrity | One 750 ml bottle per adult, in carry-on | $35 in restaurants and bars; waived with Classic or Premium package | What you can hand-carry on embarkation day |
| Princess | One 750 ml bottle per adult free to drink in cabin | Around $20 for public venues and extra bottles | Check current policy |
| Disney | One 750 ml bottle of wine or six 12 oz beers per adult, carry-on only | $20 in dining rooms | Check current policy |
Disney cut its wine allowance from two bottles to one in June 2026 and now holds port-purchased wine and beer until the end of the voyage. Royal Caribbean lets guests on back-to-back sailings bring one bottle per sailing, stored and released at the start of each new voyage, if they can show documentation for the consecutive cruises.
What happens to items confiscated on a cruise?
Most items confiscated on a cruise aren’t thrown away. They are tagged and stored, then handed back on the final night or on disembarkation morning. That usually includes:
- Returned at the end: unopened alcohol in original packaging, irons and steamers, surge protectors, speakers, some knives and tools, and alcohol bought in port or in onboard shops.
- Discarded: opened or decanted alcohol (Royal Caribbean discards seized drinks not in original unopened packaging), perishable food and fresh flowers.
- Escalated: drugs and weapons can lead to denied boarding, removal from the ship or a referral to law enforcement.
One detail most guides skip: if a banned item is in your checked bag, that whole bag may be held back from cabin delivery until you go to a security office to open it. That can cost you hours on embarkation day. Packing anything borderline in your carry-on means it is screened while you’re standing there, so a quick conversation sorts it out in minutes.
What to pack instead: a quick swap list
- Surge protector → non-surge USB charging cube (if your line allows it)
- Iron or steamer → wrinkle-release spray and the ship’s pressing service
- Candles → LED candles or battery string lights
- Plug-in fan → USB or battery clip fan
- Bluetooth speaker → headphones
- Starlink or travel router → pre-purchased ship Wi-Fi
- Bottled water → refillable bottle
- Pocket knife → small blunt scissors
- Drone → action camera or phone gimbal
- Tape-heavy decor → door magnets
If your trip is still at the planning stage, it is worth comparing lines on these policies alongside price when you browse cruise deals for 2027, particularly if bringing your own wine matters to you.
Confiscated items are usually just an inconvenience, but it’s worth knowing why cruise passengers get denied boarding, from passport problems to missing travel authorisations.
Cannabis products are among the items most likely to cause real trouble at the terminal, so read our guide to the rules on bringing weed or CBD on a cruise before you pack anything containing THC or CBD.

Usually, yes. Most items, such as unopened alcohol, irons and surge protectors, are stored and returned on the last night or disembarkation morning. Opened alcohol and perishables are discarded, and drugs or weapons can lead to denied boarding.
Can I bring a Starlink Mini on a cruise?
No, not on the major lines. Carnival and Royal Caribbean both ban satellite dishes and routers, and passengers have had Starlink devices confiscated onboard.
Is CBD allowed on cruise ships?
No. Cruise lines ban CBD and marijuana products even when they are legal in your home state or prescribed, and ports may use detection dogs.
