The ninety-second decision at the embarkation desk

You are standing at Deck 4 on boarding day. A host offers the unlimited beverage package at "today's onboard price." The line behind you is moving, the math is opaque, and the number is bigger than you expect. Most cruisers make that call on instinct, then spend the rest of the week either overpaying for drinks they did not consume or under-ordering because they know every cocktail is already adding up.
The SeaDays Drink Package Calculator exists because that guess is almost always wrong in one direction, and the direction depends on which line you are sailing, the region, and what you actually drink. A Caribbean Royal Caribbean sailing and a Mediterranean Virgin Voyages sailing do not follow the same pricing rules, so a blanket "always buy the package" or "never buy the package" rule costs money either way.
What the calculator actually does
The tool lives in Discover and takes four inputs: region, cruise line, cruise length in days, and your honest daily drink count by type — beer, wine, cocktails/martinis, and specialty coffee. It outputs three numbers: the total package cost with gratuity baked in, the total à la carte cost at your drink mix, and the break-even delta. If the delta is negative, the package loses money for you. If it is positive, you save.
Three things make the output trustworthy. First, pricing is per cruise line and per region, so Royal Caribbean's Caribbean package rate is not mixed with its Mediterranean rate. Second, currency toggles between USD, EUR, and GBP so you are comparing in the currency your shipboard folio will post in. Third, coffee is a first-class input. Specialty coffee is one of the most under-counted package drivers — two specialty drinks a day is roughly $91 a week, and leaving it out flips plenty of decisions the wrong way.
Step-by-step: running the calculator before you sail
Open Discover and tap Drink Package Calculator. Select your region (Caribbean, Mediterranean, Northern Europe, Alaska, Transatlantic, and so on). Only lines that actually sail that region appear, which cuts the noise. Pick your cruise line. Set the number of days. Use the +/– counters (capped at 15 per type so you cannot calculate a fantasy scenario) to enter the drinks you honestly expect each day.
Switch the currency to match your folio. Read the three numbers at the bottom. Screenshot the result or save your voyage context in SeaDays so the calculation is saved to the same place as your packing list and port notes. Re-run the calculator 48 hours into the cruise using data from the Drink Tracker — more on that later — and cancel the package if the numbers disagree with your early habits. Most lines allow package cancellation within a 24–48 hour window on most sailings.
Three realistic break-even scenarios
Scenario A is a 7-day Caribbean sailing on Royal Caribbean with a moderate drinker. Package runs roughly $109/day including gratuity = $763 per person. Your inputs: 2 beers at $9, 1 glass of wine at $13, 1 specialty coffee at $6.50 = about $46.50/day à la carte = $325.50 for the week. The package loses you $437. Skip it.
Scenario B is the same package price but a heavier drinker. Inputs: 2 cocktails at $15, 2 beers, 1 wine, 1 coffee = about $83/day = $581. Still under the $763 package. The package loses $182. Closer, but still skip.
Scenario C is a 7-night Virgin Voyages sailing. Virgin does not sell unlimited packages — it uses prepaid bar tabs. A $300 tab often bundles with a $50 bonus, so you are effectively spending $300 for $350 credit. Two people at $15 cocktails get 23 drinks for the week, or roughly 1.6 cocktails per person per day. If your inputs project higher, add a second bar tab. If lower, do not pre-load and pay as you go. Sizing the tab correctly instead of defaulting to "buy the biggest" saves $100–$150 per couple.
Tips experienced cruisers use
Count honestly, not aspirationally. Most cruisers overestimate cocktail consumption by about 40%. If you normally drink two beers and a glass of wine on a land vacation, enter that. Port-day consumption is usually lower than sea-day consumption because you are off the ship for six to nine hours — split the math if you want to be precise.
Specialty coffee is the silent lever. If you drink one specialty coffee a day, you are adding roughly $45–$50 a week to the à la carte side that you would otherwise miss. If you do not drink it, do not add it. A calculator that ignores your actual morning habit returns a wrong answer.
Use the Drink Tracker for 48 hours of real data, then re-run. Most package cancellations are allowed in the first 24–48 hours of a sailing. Actual early consumption patterns are a better predictor than pre-cruise guesses.
Money-saving strategies by cruise line
On Royal Caribbean, the Deluxe Beverage package break-even for most couples lands at roughly 5 drinks a day including at least two cocktails. If either person is below that, the calculator will almost always say skip. On MSC, Premium Extra includes specialty coffees and bottled water, which moves the break-even lower for coffee drinkers. On Carnival, Cheers! excludes coffee in some fare classes and includes it in others — verify before you enter inputs.
On Virgin Voyages, calculate by bar tab sizing, not by daily drink count. Carnival-style unlimited logic does not apply. On Celebrity, the Classic-to-Premium upgrade typically makes sense only if your wine preferences include bottles above the Classic cap; the calculator surfaces this with the wine counter.
Across lines, a typical moderate-drinking couple on a 7-night sailing saves between $200 and $500 by skipping the package after running the calculator honestly. Heavy-drinking couples save between $0 and $150 by buying the package. The point is not a universal rule — it is a per-sailing rule.
Real cruise scenario
A couple boards Symphony of the Seas on a 7-night Eastern Caribbean sailing. The embarkation upsell is $99/day per person = $1,386 for both for the week. They open the calculator: Caribbean, Royal Caribbean, 7 days, 2 cocktails/1 beer/1 wine/1 coffee per person per day. À la carte projection for both people: $987. Delta: package costs $399 more. They skip it.
On Day 4 they open the Drink Tracker and see real consumption: 2.1 cocktails and 1.3 beers per person per day. Re-run the calculator with actual numbers: à la carte of $1,042 for both. They saved $344 over the week by not buying. The calculator did not tell them to drink less. It told them they were already cheaper without the package.
Mistakes to avoid
Do not skip the region step — a Mediterranean Royal sailing can price differently than a Caribbean one. Do not count drinks you already have for free (status perks, Casino Royale drink offers, fare-inclusive promotions). Do not add gratuity to the à la carte side when the displayed package price already includes gratuity. Do not trust onboard "today only" urgency; terminal pricing is almost always the same as pre-cruise pricing. Do not forget specialty coffee.
Common questions

Q: Does the calculator include auto-gratuity?
A: Yes — most published package prices already include the 18% gratuity, and the calculator uses the all-in number.
Q: Can I cancel the package after boarding if the calculator flips?
A: Most lines allow cancellation within 24–48 hours of embarkation. Confirm with guest services on your specific sailing.
Q: What if my partner drinks but I do not?
A: Packages are usually sold per adult in the cabin on most lines. Run the calculator once for each person — two separate decisions, not one shared one.
Q: Are prices updated?
A: Pricing is refreshed per line and region. Run the calculator closer to sailing for the freshest numbers.
Q: What if I drink mostly bottled water and soft drinks?
A: Many packages bundle non-alcoholic options separately. Consider a soda-only or water-and-coffee bundle instead of the full bar package.
