Once you’re onboard, your cruise card becomes your wallet. A drink here, a speciality coffee there, perhaps an excursion booked on impulse — and it’s easy to stop thinking about the total.

That’s completely normal.

The good news? Cruise spending is simple to manage once you understand how the onboard account works. With a little awareness and a few deliberate decisions before you sail, the final bill should never feel like a surprise.

How the Onboard Account Works

Your Cruise Card (or Wristband)

On most cruise lines, everything you purchase onboard is charged to your cabin account. Your cruise card — or in some cases a wearable wristband — is linked to your cabin and payment method.

You won’t use cash for everyday transactions. Instead, you swipe your card and the amount is added to your onboard account.

The key thing to remember:

If you can swipe it, it goes on your cabin account.

When Charges Are Applied

Common onboard charges include:

• Daily gratuities (if not prepaid)

• Drinks and specialty coffees

• Speciality dining

• Shore excursions booked onboard

• Spa treatments and salon services

• Retail purchases

• Photography packages

Some charges appear immediately. Others (like daily gratuities) are added overnight.

When You Actually Pay

Before sailing, you’ll link a credit or debit card to your cabin account. The cruise line typically places a pre-authorisation hold at the start of the voyage.

Your final balance is settled at the end of the cruise.

You can usually monitor your balance through the cruise line’s app, your cabin television, or at guest services.

Checking it daily is one of the simplest ways to stay in control.

It’s also worth noting that pre-authorisation holds can temporarily reduce your available balance, even though they aren’t final charges.

Where Most People Overspend

Overspending on a cruise rarely happens because someone sets out to go wild.

It usually happens because spending doesn’t feel immediate.

You’re relaxed. You’re on holiday. You’re not handing over cash. And small purchases don’t feel significant in isolation.

It’s the accumulation — not the individual swipe — that catches people off guard.

Here’s where that tends to happen most often.

“It’s Only One More Drink”

A cocktail by the pool. A glass of wine with dinner. A nightcap after the show.

None of these feel excessive. And on sea days, when time feels slower and there’s nowhere else to be, it’s easy for the rhythm to continue throughout the afternoon and evening.

Without a drinks package, individual charges can quickly add up — especially when you include specialty coffees, bottled water or soft drinks alongside alcoholic beverages.

This isn’t about cutting yourself off. It’s about being aware of how quickly small, regular purchases accumulate over seven nights.

Booking Excursions On Impulse

Port talks and shore excursion presentations are designed to inspire. And they’re often genuinely helpful.

But booking excursions onboard — particularly after an enthusiastic presentation — can sometimes lead to decisions made in the moment rather than in context of your overall budget.

If you’ve researched options in advance, you’re far more likely to book intentionally. If not, it’s easy to add multiple tours without fully appreciating the total cost across the week.

Excursions are often the biggest single onboard spending category. A little planning beforehand makes a noticeable difference.

Specialty Dining Creep

Most cruises include excellent main dining options. Yet specialty restaurants are marketed as experiences — and they can be tempting.

Trying one venue feels reasonable. Trying a second feels like enhancing the holiday. By the third, you may have quietly doubled your dining spend without really intending to.

There’s absolutely nothing wrong with treating yourself. But deciding before you sail how many specialty nights feel right for your budget helps prevent the “why is our final bill so high?” moment later.

End-of-Cruise Purchases

The final days of a cruise often come with promotions — photo packages, retail discounts, clearance sales on branded merchandise.

After a great week away, emotions are high. You want something tangible to remember the trip.

That’s understandable.

But these purchases are rarely essential, and they often weren’t part of the original plan. Taking a moment before committing — even overnight if possible — prevents most last-minute regret spending.

The Pattern

In almost every case, overspending isn’t about one big decision.

It’s about multiple small, unplanned ones.

Awareness alone reduces most of this. A quick glance at your onboard account each evening keeps everything grounded in reality — and allows you to adjust gently rather than react at the end.

Simple Ways to Stay in Control

Set a Rough Daily Target

You don’t need a strict budget. But having a loose daily figure in mind makes a big difference.

Even knowing, “We’re comfortable spending around £50–£60 per day onboard” creates awareness.

For some cruises, that may feel too high. For others, particularly with specialty dining or cocktails factored in, it may be realistic. The key is choosing your number deliberately.

Check Your Account Daily

Most cruise lines make this easy. A quick check each evening keeps everything transparent.

Small adjustments early are easier than reacting at the end.

Decide Priorities Before You Sail

Before boarding, ask:

• Are we interested in speciality dining?

• Do we want a drinks package?

• Are spa treatments a priority?

• How many paid excursions do we realistically want?

Decisions made calmly at home are almost always better than decisions made impulsively onboard.

Pre-Pay Where It Makes Sense

Prepaying gratuities, WiFi or excursions in advance can make the onboard account feel simpler.

It won’t reduce total spend — but it reduces surprise.

Look for Onboard Deals (And Know When to Book)

Cruise ships operate a little like floating retail spaces. Pricing isn’t always static — and timing can work in your favour.

From experience, certain patterns repeat across most cruise lines.

Spa treatments are often discounted on port days when many guests are ashore. If you’re happy staying onboard while others explore, that’s usually when the best offers appear. In fact, remaining onboard occasionally can bring other benefits too — from quieter pools to shorter restaurant queues. (See our guide on when it makes sense to go ashore — and when staying onboard can improve your experience.)

Speciality dining packages may be promoted early in the sailing, sometimes offering better value if you book multiple venues together.

Retail promotions are also common. Themed sales often appear on sea days, and clearance-style offers may pop up towards the end of a cruise — particularly before a ship repositions or at the end of a season.

The experienced approach isn’t to chase every deal.

It’s to spend deliberately — and occasionally, strategically.

Should You Buy a Drinks Package?

Drinks packages divide opinion.

They can offer excellent value if you:

• Drink several alcoholic beverages per day

• Enjoy speciality coffees or premium soft drinks

• Prefer not to track individual purchases

However, for light or occasional drinkers, paying per drink is often more economical.

A quick break-even calculation before sailing is usually worth doing.
