Packing the right items before boarding can save you $200–$800+ per person by avoiding massively marked-up onboard purchases — the biggest wins come from bringing your own beverages, sunscreen, medications, and pre-downloading entertainment.

The cruise ship is a floating store, and everything on it costs 2–5x what you'd pay at home. The good news: a little smart packing before you leave the house can keep hundreds of dollars in your wallet instead of theirs.
How Much Can You Actually Save By Packing Smart?
Let's put real numbers on this. The average cruiser who boards empty-handed and buys everything onboard spends $150–$300 per person in avoidable purchases — and that's on a conservative estimate. Heavy drinkers, sun-seekers, and anyone with kids can blow past $500 in incidental spending without blinking.
Here's the tier breakdown of what smart packing saves you:
| Spending Category | Onboard Cost | Bring From Home | Your Savings |
|---|---|---|---|
| Sunscreen (reef-safe, 8 oz) | $22–$35/bottle | $8–$12/bottle | $10–$23 per bottle |
| Basic OTC medications (antacids, ibuprofen, Dramamine) | $8–$15/pack | $2–$4/pack | $6–$11 per item |
| Insulated water bottle + refills | $25–$40 for ship bottle | $0 if you pack yours | $25–$40 |
| Alcohol (where allowed — typically 1–2 bottles wine) | $12–$18/glass at bar | $15–$25/bottle retail | $30–$80+ per cruise |
| Travel-size toiletries (shampoo, conditioner, lotion) | $6–$12/item at gift shop | $1–$3/item at home | $10–$30 |
| Formal night outfit (bought onboard) | $80–$200+ | $0 if you pack it | Up to $200 |
| Soda/water (canned or bottled) | $3–$5/can or bottle | $0 if you pack allowed quantities | $30–$100+ |
| Streaming/entertainment downloads | N/A (Wi-Fi needed = $25–$35/day) | $0 if pre-downloaded | $75–$245 |
| Power strip (no surge protector) | $20–$35 onboard | $8–$15 | $5–$20 |
| Total potential savings | $200–$800+ per person |

Key Factors That Drive What You Should Pack
Your cruise line's carry-on beverage policy is the biggest variable. Royal Caribbean, Carnival, Norwegian, and Princess all allow passengers to bring a limited quantity of non-alcoholic beverages (typically a 12-pack of canned sodas or water per person at embarkation). Carnival and some others allow 1–2 bottles of wine per stateroom. Bringing a $15 bottle of Prosecco instead of paying $14/glass at the bar is one of the highest-ROI moves in cruise travel.
Port destination changes what you need. Caribbean itineraries = bring industrial-strength sunscreen. Alaska = pack layers and rain gear instead of buying a $75 fleece onboard. Mediterranean = comfortable walking shoes matter more than a beach bag.
Length of sailing multiplies every cost. On a 3-night Bahamas cruise, skipping the ship's spa toiletries costs you $10. On a 14-night transatlantic, that habit costs you $60+.
Family size is a force multiplier. A family of four buying Dramamine onboard ($12/pack × 4 = $48) vs. bringing one value pack from Costco ($8 total) is a perfect microcosm of how ship markup works at scale.

Practical Tips: What to Pack and Exactly How It Saves You Money
1. Bring a no-surge-protector power strip. Cabins typically have 1–2 outlets max. A plain power strip (no surge protection, which ships prohibit) costs $10 on Amazon. Charging 4 devices at once means you're not hunting for adapters at the gift shop.
2. Pack a refillable insulated water bottle. Every major cruise line has free water at the buffet and water stations. A $15 Hydro Flask keeps it cold all day. Compare that to $3.50/bottle of ship water or the $75–$95/person/day Deluxe Beverage Package if you were only buying it for the water and soda.
3. Load your devices before you board. Download Netflix episodes, Spotify playlists, Kindle books, and podcasts while you're still on land. Ship Wi-Fi runs $25–$35/day and is notoriously slow. Pre-downloading eliminates the temptation entirely.
4. Pack your formal or elegant night outfit. If your itinerary has a formal night (most 7-night+ sailings do), wearing something you already own instead of buying a dress or renting a jacket onboard saves $80–$200 easily.
5. Bring a small first-aid and medication kit. The ship's medical center is for emergencies — but the gift shop medical section is a shakedown. Pack: ibuprofen, antacids (Tums), Dramamine or meclizine for seasickness, allergy meds, Band-Aids, and a thermometer. Total cost at home: $20–$35. Buying the same items onboard: $60–$100+.
6. Pack your own snorkel gear if you're doing water activities. Shore excursion operators and ships charge $15–$30/day to rent a basic snorkel set. A decent mask-and-snorkel combo costs $20–$40 on Amazon and lasts for years.
7. Bring a small day bag or backpack. Ships sell tote bags for $25–$45. You need something for port days. Pack a foldable daypack — it weighs nothing and saves you from impulse-buying the branded version.
8. Check your cruise line's beverage carry-on policy and use it. Here's the 2025 policy cheat sheet for major lines:
| Cruise Line | Non-Alcoholic Beverages | Wine/Champagne Policy |
|---|---|---|
| Carnival | 12 cans/cartons per person at embarkation | 1 bottle of wine or champagne per person (21+) |
| Royal Caribbean | 12 cans (non-alcoholic) per person | 2 bottles of wine per stateroom |
| Norwegian | Non-alcoholic allowed; quantity limits apply | No alcohol carry-on |
| Princess | 1 case (12 cans) non-alcoholic per person | 1 bottle wine per person |
| Celebrity | Non-alcoholic allowed | 2 bottles wine per stateroom |
| MSC | Non-alcoholic allowed | 1 bottle wine per cabin |
| Disney | Non-alcoholic reasonably; 2 bottles wine per stateroom | 2 bottles wine per stateroom |
9. Bring a small combination lock. Some ships have safes; some don't have good ones. A $10 TSA-approved luggage lock protects your valuables in port without paying for a ship locker.
10. Sunscreen — buy the maximum you think you need and then double it. Onboard sunscreen is priced as a luxury item. Budget $10–$15 at home vs. $25–$35 onboard, and on a 7-day Caribbean cruise, a family of four can go through 4+ bottles.
The Items NOT Worth Bringing From Home
Not every onboard purchase is a ripoff. Skip packing:
- Formal photography setups — the ship photographers are actually decent and packages can be reasonable if you negotiate on the last night
- Tons of cash for tips — use your onboard account or pre-pay gratuities at booking
- Excessive board games or books — the ship library and activities cover this; space in your bag is valuable
The goal isn't to pack your entire house. It's to neutralize the 5–10 categories where the ship has you completely captive and prices it accordingly.
Before your next sailing, run your itinerary through CruiseMutiny to see exactly which onboard costs are worth paying for and which ones you should bring from home — because the difference between a smart packer and an impulse buyer on the same 7-night Caribbean cruise can easily be $400–$600.
