Packing for a cruise often feels like negotiating with yourself. You want comfort, the little things that make a cabin feel like home, but the rules of a floating city are strict. According to CLIA’s 2024 State of the Cruise Industry report, more than 31.7 million passengers sailed worldwide in 2023, up 7% from the pre-pandemic peak.
With capacity expected to grow another 10% by 2028, cruise staff face a steady flow of bags to screen. Many passengers are younger, too: nearly 36–42% are under 40, with Millennials at 22% and Gen Z at 14% of total travelers.
Understanding what lines will and won’t allow is as much about safety and law as it is about keeping such a bustling, multi-generational space calm.
Alcohol and Booze Beyond the Rules
Bringing alcohol onboard might feel harmless, especially if it’s a small bottle of wine tucked into your suitcase. Cruise lines, however, have precise rules. Royal Caribbean allows only a limited amount of wine or Champagne in original, sealed bottles, warning that beer or liquor beyond policy “will be confiscated and returned after the cruise,” according to their 2025 guidance reported by LadBible.
CBD and cannabis products are treated even more strictly. Carnival explicitly notes that CBD is illegal under U.S. federal law and in many ports of call, and one traveler in 2023 faced a lifetime ban for carrying gummies, Islands reports.
Weapons, Self-Defense Items, and Sharp Objects
Knives, stun guns, brass knuckles, martial arts weapons—even playful handcuffs—are forbidden aboard most ships. Royal Caribbean’s conduct policy explicitly bans weapons, ammunition, explosives, and other dangerous items, emphasizing passenger safety.
Reddit threads describe the “naughty table,” where confiscated but non-illegal items—clothing irons, surge protectors, humidifiers—are laid out for pickup at disembarkation. One post notes seeing dozens of irons, multi-tools, and even a lawn sprinkler.
Clothing Irons, Steamers, and Fire-Risk Appliances
Cruise lines are cautious about anything generating heat in cabins. TouringPlans and CruiseBooking explain that cruise lines ban clothing irons, steamers, coffee makers, kettles, candles, heating pads, and electric blankets. RoyalCaribbeanBlog describes irons and steamers as among the most commonly confiscated items at embarkation.
Disney Cruise Line goes further, limiting hair dryer wattage, with confiscated devices returned only at the end of the voyage, according to InsideTheMagic. The rationale becomes clear when imagining hundreds of guests crammed into small, wired spaces.
According to CruiseBooking, these items are among the most commonly confiscated and returned only after the trip. Safety takes precedence over comfort, and shared spaces demand rules that might feel inconvenient but protect everyone onboard.
Drones and High-Tech Gear
Drones, routers, and satellite equipment are treated with extra caution. Royal Caribbean lists drones alongside devices that could interfere with ship systems or pose safety hazards. YouTube cruise vloggers have documented thousands of dollars’ worth of drone equipment being confiscated at boarding and stored until disembarkation. CruiseCritic notes that drones, in particular, carry risk: they might fall overboard, crash on deck, or disrupt navigation.
Even devices meant for fun or photography can become liabilities. Lines store or restrict these items, allowing supervised use ashore. With ships serving millions of tech-savvy passengers, the measures reflect a balance between personal expression and collective safety, a compromise between freedom and responsibility that you feel quietly as your suitcase is screened.
Bluetooth Speakers and Sound Machines
Sound travels quickly on a ship, and personal devices can intrude on everyone else’s experience. In late 2024, Carnival Cruise Line officially banned Bluetooth speakers, radios, and portable sound devices. Carnival’s 2024 social media poll of over 15,000 passengers revealed that 90% favored banning Bluetooth speakers entirely, according to CruiseFever.
CruiseCritic further reports that boom boxes, radios, and even toddler white-noise machines are confiscated and held until the end of the cruise. Carnival’s brand ambassador, John Heald, explained that using personal speakers on balconies is “well selfish,” noting the need to hear announcements and maintain calm.
Power Strips, Surge Protectors, and Multi-Plug Devices
Cabins are small, wired, and shared. Royal Caribbean warns that multi-plug outlets, surge protectors, and travel routers now fall under the banned items due to fire risk and interference with onboard systems.
Photos from 2025 show confiscated items stacked on tables like tiny, humbling monuments to convenience. CruiseBooking highlights how travelers treat cabins like home offices or nurseries, connecting devices freely. Lines respond by reclaiming electrical order, gently reminding guests that safety and harmony in a steel city at sea matter more than personal convenience.
Perishable Food and Certain Snacks
Cruise lines also restrict what you can bring to eat. CruiseCritic explains that fresh produce, meats, and homemade foods are typically banned due to pest control, food safety, and agricultural regulations in ports of call. Sealed snacks are usually safe, but most perishable items are confiscated and often not returned.
The rule extends beyond the ship itself: Caribbean authorities, for example, restrict certain foods and clothing, such as camouflage clothing, for civilians. Royal Caribbean’s guidance flags clothing and accessories that may be illegal in certain ports. Your bag, it turns out, negotiates not only with cruise security but also with distant port regulations, a quiet reminder that travel always involves unseen boundaries.
Household Appliances and Specialty Smoking Gear
If an item belongs in a kitchen or garage, it likely belongs on the banned list. CruiseBooking and LadBible list coffee machines, rice cookers, immersion heaters, hoverboards, car batteries, hookahs, and large vaporizers as prohibited. These items combine fire risk, smoke concerns, and electrical strain.
Smoking itself is tightly regulated and restricted to designated outdoor areas. Cruise lines frame these bans as preventive measures rather than reactions. Safety policies evolve alongside passenger habits, tightening where convenience collides with risk.
Marijuana, CBD, and “Wellness” Products
What feels harmless at home often turns serious at sea. CruiseBooking and Royal Caribbean policy explainers state clearly that marijuana and CBD products are prohibited, even when legal in a traveler’s home state. Islands reports Carnival Cruise Line’s warning that CBD remains illegal under U.S. federal law and in many ports of call.
One passenger was reportedly banned for life after bringing CBD gummies onboard in 2023. At sea, federal law applies, and ships visit international ports with stricter drug regulations. Cruise Hive notes that suspected narcotics are not simply confiscated but handed to law enforcement. What looks like a wellness habit on land becomes a legal risk once borders blur.
Key TakeAways
Perhaps the most human lesson is found in the “Naughty Room,” a temporary holding space for seized items that are legal but not allowed. Reddit users report seeing dozens of clothing irons, power strips, humidifiers, handcuffs, and even lawn sprinklers lined up for pickup (Reddit, 2025).
Islands notes that liquor and perishables often disappear, but other items are returned after the voyage. The system is not about embarrassment. It is about keeping millions of strangers safe inside a moving city, where small risks multiply fast.
