Yes, you can bring and spend cash on a Carnival cruise, but the ship runs mostly on a card system

Carnival allows cash aboard, and you can use it at bars, restaurants, gift shops, and other onboard venues. However, the ship operates primarily on a Sail & Sign card — a keycard that charges purchases to your account. Most passengers find they need very little cash because nearly everything can go on the card, which you settle when you leave the ship.

If you do bring cash, keep in mind that Carnival does not exchange foreign currency onboard, and ATMs on the ship charge fees. The practical approach for most cruisers is to bring a modest amount of cash for tips, small purchases, or emergencies, and rely on your Sail & Sign card for the rest.

Key Takeaways

  • Your Sail & Sign card is the primary payment method onboard; you can charge almost all purchases to it and pay one bill at the end of your cruise.
  • Cash is accepted at bars, restaurants, shops, and casinos, but you do not need much because the card works nearly everywhere.
  • Onboard ATMs charge withdrawal fees, so bringing cash from home is cheaper than using the ship's machines.
  • Tipping staff with cash is common and appreciated, though you can also add gratuities to your final bill.
  • Foreign currency cannot be exchanged on the ship, so convert money before boarding or plan to use your card.

How the Sail & Sign card works

When you board a Carnival ship, you receive a Sail & Sign card that acts as your room key and payment method. Every purchase you make — drinks, dining, excursions, spa services, photos — is charged to this card. You do not pay for individual items as you go; instead, charges accumulate and you receive one itemized bill when you disembark.

The card is linked to a credit card or debit card you provide during check-in. If you want to pay with cash instead, you can set up a cash deposit at the purser's desk when you board. The purser holds your cash and deducts charges from it as you spend. Any remaining balance is refunded to you in cash when you leave.

This system means you rarely need to carry cash around the ship. Your keycard is safer, easier to track, and you get an itemized record of everything you spent.

Where cash is accepted onboard

Cash works at most venues on the ship, including bars, casual dining areas, the buffet, gift shops, the casino, and spa services. Some specialty restaurants and premium dining packages may require the card, so check your cruise documents or ask at the venue if you are unsure. Vending machines typically accept cards only, not cash.

If you prefer to pay cash for a specific purchase, you can do so, but the transaction is still recorded on your account. The purser will deduct the amount from your cash deposit. This hybrid approach — mixing cash and card — works fine, though most passengers find it simpler to just use the card for everything.

Bringing cash versus using onboard ATMs

Bringing cash from home is cheaper than withdrawing it from an ATM on the ship. Carnival's onboard ATMs charge a fee for each withdrawal — typically $3 to $5 per transaction, plus any fee your own bank charges. If you need $100 in cash, you might pay $6 to $10 in fees alone.

A better approach is to withdraw cash at your bank or an ATM before you board. Bring what you think you will need for tips, small purchases, and emergencies. For most cruisers, $50 to $100 in cash is plenty, since the card covers nearly everything else.

If you do run short on cash during the cruise, the ATM is available, but plan for the fee. The purser's desk can also help you access funds if you have a problem with your card.

Tipping with cash versus adding to your bill

Tipping housekeeping and dining staff is customary on cruises. You can tip in cash by leaving money in your cabin or handing it directly to staff, or you can add gratuities to your final bill. Carnival's standard gratuity is about $15 per person per day, though you can adjust this amount or add extra tips as you wish.

Many passengers prefer to tip in cash because staff receive it when ready and directly. If you plan to do this, bring extra cash beyond what you need for purchases. A few dollars per day for your cabin steward and dining server adds up quickly, so budget accordingly.

If you do not bring enough cash, you can always add tips to your bill at the end of the cruise. The choice is yours, and either method is acceptable.

Foreign currency and currency exchange

Carnival does not exchange foreign currency onboard. If you are boarding from a port outside the United States or plan to visit ports that use different currencies, exchange your money before you board or at the port itself.

For ports of call, you can use your Sail & Sign card at many shops and restaurants, though some smaller vendors may accept cash only. Bring local currency for those situations, or ask your shore excursion guide what payment methods work at your destination. The purser's desk can advise you on currency needs for your specific itinerary.

What happens if you lose your cash or card

If you lose cash, it is gone — the ship cannot replace it. If you lose your Sail & Sign card, go to the purser's desk when ready and they will issue a replacement. Any charges made on the lost card after you report it are not your responsibility.

This is another reason many cruisers prefer the card system: it is safer than carrying large amounts of cash. If you are worried about losing your card, keep it in your cabin safe when you are not using it, just as you would with a credit card at home.

Frequently Asked Questions

Do I have to use a credit card to set up my Sail & Sign account?

No. You can deposit cash at the purser's desk when you board, and charges will be deducted from that cash balance. Any remaining cash is refunded when you leave. A credit or debit card is the default option, but cash works fine if you prefer it.

Can I use cash at specialty restaurants or premium dining packages?

Most specialty restaurants and paid dining packages require the Sail & Sign card, though some may accept cash. Check your cruise documents or ask at the restaurant when you board. If you want to pay cash, confirm this in advance with the purser so there are no surprises.

What if I run out of cash during my cruise?

Use the onboard ATM to withdraw more, though you will pay a fee. Alternatively, ask the purser if you can add more cash to your account. Since the card covers almost everything, running out of cash is usually not a problem unless you planned to tip entirely in cash.

Is it safe to carry cash around the ship?

The ship is generally safe, but carrying large amounts of cash is unnecessary since the card works almost everywhere. Bring only what you need for tips and small purchases, and keep the rest in your cabin safe. This reduces the risk of loss or theft.

Can I use my Sail & Sign card at ports of call?

Your Sail & Sign card only works onboard the ship. At ports, use cash, a credit card, or a debit card depending on what the vendor accepts. Ask your shore excursion guide what payment methods are common at your destination.
