Stacking Casino Offers Across Sailings: A Worked Example

Three offers, three legs, one home port — how to assign each certificate to the right sailing so a three-week run costs the least out of pocket.

Theory is nice; let’s do a real one. Say you’re holding three Club Royale comp offers, all valid out of Miami this fall, and you want to sail as long as you can for as little as possible. The order you spend them in is not obvious, and getting it wrong can cost real money. Here’s how to reason about it.

The pieces

Three offers, simplified:

1. Offer A — comps the fare on select 7-night Western Caribbean sailings, second guest ~60% off.
2. Offer B — comps the fare on 5-night sailings, second guest full fare.
3. Offer C — a $200-off discount valid on almost anything, second guest included.

And a ship, the Freedom of the Seas, alternating a 5-night Western and a 4-night Bahamas week out of Miami, so consecutive sailings connect cleanly port-to-port.

The naive plan

Spend them in the order they arrived: A on the first available week, B on the next, C on the third. The problem: Offer A is your most valuable certificate (a full 7-night comp), and if the first available week is a short 5-night sailing, A can’t even be used there — it’s only eligible on 7-night Westerns. Spend offers in inbox order and you routinely waste your best one.

The right way to think about it

Match each offer to the leg where it saves the most, subject to what it’s eligible for:

• Offer A only fits a 7-night Western — so it goes on the one week that qualifies, no choice, and it’s worth the most there anyway.
• Offer B fits the 5-night legs and comps the whole fare — put it on the priciest 5-night week in your range, because a full comp is worth more on an expensive sailing than a cheap one.
• Offer C is only $200 off, so it goes on whatever’s left — ideally a leg where $200 is a big slice of the fare, and where the second guest matters (since C includes them).

That reshuffle — A on the 7-night, B on the expensive 5-night, C on the cheap leftover — can be a few hundred dollars better than inbox order across a three-week run. Multiply that over a year of offers and it’s the difference between one extra free cruise and none.

The offers don’t care what order they arrived in. Spend them where they save the most, not where they showed up.— Otto Pilot

Where the math gets hard

With three offers and three legs you can reason it out on a napkin. With five offers, two travelers who each have their own offers, eligibility lists that overlap, and a dozen candidate sailings, the combinations explode — and that’s before you check which sailings even chain together. This is precisely the assignment problem Leg to Leg Cruises solves: it takes your real offers, their real eligible-sailing lists, and every chain from your port, and works out which certificate belongs on which leg to minimize what you pay.

You can absolutely do it by hand. I did, for years, in a spreadsheet I’m still slightly proud of. But the first time you watch the optimizer find a better assignment than the one you’d penciled in, the spreadsheet starts to feel like doing long division for fun.
