It’s the last night of the cruise. Your skin is a little pink, your phone is at 4 percent, and a cheerful person at a small desk asks if you’d like to book your next trip right now. Most passengers smile and keep walking toward the buffet.
They may be walking past real money. Cruise lines write actual perks around that desk, from tiny deposits to onboard credit, and they rarely advertise them loudly. But the rules change from line to line, and one of the biggest numbers on this list isn’t quite what it looks like. Here’s what the cruise lines’ own published terms say.
#13 – The “Book Now, Pick Later” Trick That Lets You Lock In a Deal Without a Date

MSC’s Open Booking Program gives guests up to a year to decide on a destination and travel dates. You get the onboard-only offer before you’ve even looked at a calendar. Celebrity’s Book Later option gives you six months to finalize your plans with a nonrefundable deposit.
Royal Caribbean has run a version too. Its Book Later option has required a $200 non-refundable deposit per stateroom and promised up to $600 in onboard credit or instant savings if you pick a sailing within two months. The windows range from two months to a year depending on the line, so check yours before you sign.
But the next perk is the one that gets people to the desk in the first place…
#12 – Deposits That Shrink to as Little as $100 a Person

Putting less money down is the most common onboard perk. MSC says you can secure a booking with a deposit as low as $100 per person. Princess’s Future Cruise Deposit is a reduced $100 per person that holds your booking until final payment.
Holland America follows the same pattern. Its reduced deposits start at $100 per person for cruises of up to 21 days, then climb to $300 for 22 to 50 days and $1,000 for 51 days or longer. Cheap to start, but the longest voyages still cost more to hold.
Quick Compare
- MSC: deposits as low as $100 per person
- Princess: $100 per person, held until final payment
- Holland America: $100 per person for up to 21 days
- Holland America, long voyages: $300 for 22 to 50 days, $1,000 for 51 days or more
Not everyone thinks these small deposits are a bargain. Some veteran cruisers argue that tying up money a year or more ahead just hands the cruise line a free loan. Others say the credit is worth it. Where you land depends on how sure you are about sailing again.
Then there’s the perk that actually puts spending money in your pocket…
#11 – Instant Onboard Credit, Up to $500 on Some Lines

This is the headline perk, and it’s real. Celebrity’s Book Now and Book Later offers include up to $500 in onboard credit, based on cabin category and length of sailing. MSC advertises up to $300 in onboard credit per stateroom.
Princess is smaller, with up to $150 in onboard credit tied to its Future Cruise Deposit. Remember that this is spending money for the next trip, not cash. It goes toward things like spa treatments, specialty dining and drinks, so it only pays off if you’d spend that money onboard anyway.
And the amount you get can change wildly depending on one detail most people overlook…
#10 – Credit That Grows With the Length of Your Next Trip

Many programs reward longer sailings with bigger payouts. Holland America pays $50 to $150 per person for cruises of three to 10 days, $125 to $250 for 11 to 21 days, $225 to $375 for 22 to 50 days, and $350 to $500 for 51 days or more. That scale quietly nudges you toward a longer itinerary.
Virgin Voyages uses the same logic. On a 4-to-5-night voyage, the offer saves $150 on the fare and adds $150 in onboard credit, a total value of $300. The longer the voyage, the more the offer is worth.
Here’s a safety net you probably didn’t know existed…
#9 – The Deposit That Comes Back If You Never Book

Some onboard deposits are built to be refunded. With Princess, if you don’t book within the window, the Future Cruise Deposit is automatically refunded to the credit card you used. You have up to a year to book.
Holland America’s version is more generous. If you put down an open-ended deposit and don’t choose a cruise within four years, the deposit is refunded rather than lost. Cruise Critic notes that at one line, deposits minus the instant onboard credit are refundable within 30 days, which means you may not get back everything you paid.
Worth Knowing
- Princess: unused deposits go back to the card you paid with
- Holland America: refunded if you don’t pick a cruise within four years
- One line, per Cruise Critic: the refund can exclude the instant onboard credit
- Royal Caribbean NextCruise: the deposit is not refundable at any time
The surprise isn’t that refunds exist. It’s how different the rules are from one line to the next, so the headline perk and the refund terms aren’t always a package deal.
If that sounds generous, wait until you see how long some of these deposits last…
#8 – Deposits That Stay Valid for Four Years

Holland America has one of the longest expiration dates among onboard booking perks, with deposits valid for four years. That’s longer than most people can say they plan their vacations.
Cunard has also published long terms. Its future cruise deposits have expired four years from the date of issue and have been fully refundable. Compare that to Princess’s one-year window, and you can see how much the timelines vary.
But there’s a booking shortcut hiding in the fine print too…
#7 – Your Travel Agent Can Often Take It Over

Many cruisers assume that booking onboard means cutting out the travel agent. Often it doesn’t. Holland America lets you put the booking under your travel agent’s name so they can handle the reservation and final payment.
Princess allows it too. You can book your cruise with your preferred travel advisor, a Cruise Vacation Planner, or directly through Princess. A published guide from Travel Market Report has also noted that one line’s CruiseNext deposit booking transfers automatically to the travel advisor within 10 days after the cruise.
Whether you actually need an agent is debatable, and some cruisers swear by booking direct. But the onboard offer doesn’t force that choice.
Now for a perk that comes as a straight percentage off…
#6 – A Quiet Percentage Off the Fare

Some lines skip the gimmicks and just take money off. AmaWaterways guests can pay a $100 per person deposit in return for a Future Cruise Savings certificate worth 5 percent off the voyage fare on certain sailings.
Azamara works similarly. Guests receive a 5 percent discount, and Azamara Circle members get an additional 5 to 10 percent depending on status. Travel Market Report’s published policies also listed Carnival guests keeping a 2.5 percent savings even after changing their booked sailing outside the cancellation period. That Carnival detail comes from an older policy summary, so confirm current terms.
And the real question is whether these deals can be combined…
#5 – Stacking the Onboard Offer on Top of Other Promotions

Some lines let the onboard perk ride alongside whatever sale is running. Travel Market Report’s policy roundup noted that Carnival’s offer was combinable with all other applicable savings and promotions. Oceania’s was listed as combinable with current promotions.
Not every line plays along. The Points Guy reported that one program’s onboard credit couldn’t be stacked with loyalty status offers or other special rate classes. So stacking is a line-by-line question, not a universal rule.
Next up is the person who is actually paid to help you with all of this…
#4 – A Dedicated Consultant and the “Best Offer” Promise

Booking onboard puts you in front of someone whose entire job is future sailings. Holland America’s onboard future cruise consultant can get you onboard credit and a reduced deposit. Virgin Voyages sends you to Future Voyages on Deck 7, Midship, for personalized assistance.
Celebrity goes further with its marketing. The Points Guy reports you’re guaranteed the best promotional fare available when you book through its program. If you choose Book Later, you don’t need to make an appointment with a consultant. That promise is worth checking against what’s online before you sign.
Fast Facts
- Holland America: an onboard consultant can arrange credit and a reduced deposit
- Virgin Voyages: Future Voyages is on Deck 7, Midship
- Celebrity Book Later: no consultant appointment needed
- Celebrity’s pitch: the best promotional fare available, so compare it online
The next perk has nothing to do with your cabin at all…
#3 – Shore Excursion Savings You Can Lock In While Still Aboard

One of the quieter perks targets what you do in port. Travel Market Report’s roundup listed an Oceania Cruises perk that saves you up to 10% off future shore excursions when you pre-plan them while onboard your current ship. It also listed a $100 onboard credit if you select a sailing within two months of putting down a deposit.
That policy summary is a few years old, so treat the exact numbers as a starting point. The idea still shows how creative these programs get. Excursions are often among the priciest parts of a trip, so a discount there can matter.
But the biggest flexibility perk is one almost nobody asks about…
#2 – The Freedom to Change Your Ship or Date Without Losing the Perk

Plans change, and some lines build that in. One published set of terms says changes to the ship or sail date of a confirmed booking can be made once, before final payment, without a change fee and without losing the onboard booking offer. That’s a real safety valve.
Royal Caribbean’s NextCruise terms look different. Changes to Book Now bookings, including ship or sail date, made two months or more after creation are subject to change fees. And the deposit rules are strict: the deposit is not refundable at any time. Same idea, very different level of freedom.
At a Glance
- The flexible version: one change before final payment, no fee, offer kept
- The stricter version: Royal Caribbean charges change fees after the two-month mark
- The deposit catch: Royal Caribbean’s NextCruise deposit is never refundable
Which brings us to the offer that makes the others look small…
#1 – A $150 Deposit That Can Unlock Up to $500 in Value

The most eye-catching math comes from Virgin Voyages. Its offer promises $500 in onboard credit when you put down a $150 deposit for your next getaway. You have two years to book and sail with the perks you scored.
But the value is a mix of fare savings and credit, and it scales with the voyage. A 4-to-5-night sailing earns $300 in total value, not $500. Fine print matters everywhere: Holland America’s perks, for example, don’t apply to cruises shorter than three days, world cruises or Grand Voyages. The biggest number is rarely the one you’ll get.
So is booking onboard worth it, or just a clever sales pitch? Sometimes both. Reduced deposits, onboard credit, small discounts and long booking windows are all written into real policies. But the perks vary a lot by line, and some deposits aren’t refundable at all. Royal Caribbean’s NextCruise terms say so plainly, while Princess and Holland America can return your money.
Cruise Critic’s summary is a good rule of thumb: terms vary by cruise line and offer type. Read the refund and change rules before you hand over a card, and that little desk by the buffet stops being a mystery. Which of these perks would actually get you to book on the spot?
