What We Wanted to Find Out
Every cruise article says the same thing: book shoulder season, save money. We wanted to know if that’s actually true — not as a general rule, but with real numbers. So we went straight to Royal Caribbean’s own booking pages and pulled prices for five real sailings across four regions, comparing peak summer against shoulder season.
The results weren’t what we expected. Some regions saved money exactly as predicted. One gave us two completely different answers depending on which port the ship sailed from.
How We Compared Royal Caribbean’s Prices
Every price below comes directly from Royal Caribbean’s own pricing pages — no aggregators, no third-party estimates. All prices include taxes and fees, giving a more realistic picture of the advertised total than a base-fare comparison would.
A note on cabin type: these are Royal Caribbean’s advertised “from” prices, reflecting the cheapest available cabin at the time of checking. Availability shifts constantly, so treat these as a snapshot rather than a permanent rate — and where the same ship sailed the same itinerary in both periods, we’ve said so; where the comparison uses different ships or itineraries, we’ve flagged that too.
Mediterranean: A Modest 10% Saving in October
Legend of the Seas, sailing 7-night round-trip itineraries from Barcelona, was priced at $2,065 per person for a July 25, 2027 departure — about $295 per night. An October 10, 2027 departure was priced at $1,860 — about $266 per night. That’s a 10% saving.
Of all the comparisons in this article, the Mediterranean showed the smallest shoulder-season saving — real, but modest compared to the Greek Isles or Caribbean numbers.
Greek Isles & Adriatic: 22% Cheaper in October
This one-way repositioning itinerary sails from Athens (Piraeus) to Ravenna, Italy, calling at Rhodes, Mykonos, and Santorini before crossing into the Adriatic. On the identical ship, a July 12, 2027 departure priced at $1,175 per person — working out to roughly $168 per night. An October 4, 2027 departure priced at $919 — about $131 per night. That’s a 22% drop, the largest shoulder-season saving of any comparison in this article.
It’s worth noting the itineraries differ slightly in their Croatian stops (Split and Zadar in July; Split and Dubrovnik in October), so this isn’t a perfectly identical route — but it’s close enough, on the same ship, to make the price gap meaningful.
Alaska from Seattle: Shoulder Season Cost More
Here’s where the pattern broke. Voyager of the Seas sailed the identical 7-night Alaska round-trip from Seattle (Juneau, Skagway, Endicott Arm & Dawes Glacier, Victoria) in both July and September 2027. A July 30 departure priced at $809 per person — about $116 per night. A September 3 departure priced at $861 — about $123 per night, 6% higher.
Alaska from Vancouver: 23% Cheaper in September
Same region, same season, completely different port — and a completely different answer. Serenade of the Seas sailed the identical 7-night Alaska round-trip from Vancouver (Inside Passage, Sitka, Tracy Arm Fjord, Ketchikan, Prince Rupert) in July and September 2027. A July 11 departure priced at $1,025 per person, about $146 per night. A September 19 departure priced at $792 — about $113 per night, a 23% drop.
Read those two Alaska comparisons side by side and the real finding of this article comes into focus: it isn’t Alaska alone that decides the season’s pricing pattern — the departure port made a measurable difference too. Seattle sailings got more expensive from July to September; Vancouver sailings, on the same cruise line, in the same year, got dramatically cheaper.
Caribbean: A Near-Clean Comparison, With One Caveat
This one comes close to matching the other four, but not quite. Icon of the Seas sailed the identical 7-night Eastern Caribbean itinerary from Miami (St. Maarten, St. Thomas, Perfect Day CocoCay) in both periods we checked — but the two dates fall in different years. A July 31, 2027 departure priced at $1,989 per person, about $284 per night. An October 24, 2026 departure — a year earlier — priced at $1,470, about $210 per night, a 26% difference.
Because the comparison spans two different years rather than the same year like our other four, some of that gap could reflect broader year-over-year pricing changes rather than pure seasonality — a limitation the other comparisons in this article don’t have. We looked for a same-year October 2027 sailing on this exact itinerary and couldn’t find one; other Caribbean prices we found for October 2027 used different ships, different ports, or different itinerary types entirely.
The Full Comparison
| Region | Ship(s) | Peak season | Shoulder season | Per night (peak → shoulder) |
|---|---|---|---|---|
| Mediterranean | Legend of the Seas (same ship) | $2,065 — Jul 25 | $1,860 — Oct 14 | $295 → $266 |
| Greek Isles & Adriatic | Explorer of the Seas (same ship) | $1,175 — Jul 12 | $919 — Oct 4 | $168 → $131 |
| Alaska (Seattle) | Voyager of the Seas (same ship) | $809 — Jul 30 | $861 — Sep 3 | $116 → $123 |
| Alaska (Vancouver) | Serenade of the Seas (same ship) | $1,025 — Jul 11 | $792 — Sep 19 | $146 → $113 |
| Caribbean* | Icon of the Seas (same ship) | $1,989 — Jul 31, 2027 | $1,470 — Oct 24, 2026 | $284 → $210 |
*Same ship and itinerary, but the two dates span different years — treat this one with slightly more caution than the other four.
Four of our five comparisons showed shoulder-season savings; Alaska’s Seattle sailing was the one clear exception.
Why Departure Port Matters as Much as Region
Why the Seattle and Vancouver prices moved in opposite directions is genuinely hard to say with certainty. Demand patterns, remaining cabin inventory at the moment we checked, small itinerary differences, and booking timing can all affect Royal Caribbean’s advertised starting prices — and we can’t isolate which of those factors mattered most from pricing snapshots alone.
What we can say is that Seattle and Vancouver are different gateways with different itineraries and, often, different traveller profiles — Seattle round-trips tend to be the more mainstream option, while Vancouver’s Inside Passage routing has a slightly different draw. Whatever the underlying cause, the practical lesson holds regardless: a regional rule of thumb can mask two genuinely different local markets.
What This Means for Booking Your Own Cruise
Don’t book on the assumption alone. Four of our five comparisons here showed meaningful shoulder-season savings — up to 23% in the same-year comparisons, and 26% in the year-over-year Caribbean comparison — genuinely worth chasing if your dates are flexible. But Alaska’s split result is a reminder that “region” isn’t always the right unit of comparison; the departure port can matter just as much as the month. If you’re planning an Alaska cruise specifically, check pricing for your exact port and ship rather than assuming the whole region moves together.
FAQ: Cruise Prices by Season
Is it always cheaper to cruise in shoulder season?
Usually, but not always. In four of our five comparisons, shoulder season was cheaper, with savings of up to 23% in the same-year comparisons. But an Alaska sailing from Seattle priced 6% higher in September than in July, while the Mediterranean showed the smallest saving at 10% — proof the general rule has exceptions, even within a single region.
Which cruise had the biggest shoulder-season saving?
A Greek Isles and Adriatic sailing on Explorer of the Seas, from Athens to Ravenna, showed the largest gap: $1,175 in July versus $919 in October, a 22% saving on the identical ship and nearly the same itinerary.
Is an Alaska cruise cheaper from Seattle or Vancouver?
It depends on the month you’re comparing, not just the port. Our data showed Seattle sailings getting slightly more expensive from July to September, while Vancouver sailings dropped sharply over the same period — check both gateways directly rather than assuming one is always cheaper.
How much cheaper is an October Mediterranean cruise than July?
On the Legend of the Seas sailing we checked, from Barcelona, October priced about 10% lower than July — the smallest saving of any region in our comparison, but still a real difference. That doesn’t mean the Mediterranean never has a shoulder-season discount — other ships and itineraries may show a larger gap — but it’s a reminder to check the actual sailing rather than assume.
Are Caribbean cruises cheaper in October?
Our data suggests yes — Icon of the Seas priced 26% lower on an October date than a July date for the identical Miami itinerary. The comparison isn’t perfectly clean, since the two dates fall a year apart, but it points in the same direction as most of the other regions we checked.
The Bottom Line
“Book shoulder season to save money” held up in most of our comparisons. The same-year comparisons showed savings of up to 23%, while the year-over-year Caribbean comparison showed a larger 26% gap. But Alaska’s split result — cheaper from Vancouver, more expensive from Seattle, in the same year, on the same cruise line — is the finding we didn’t expect and the one worth remembering: check the actual ship, port, and date, because sometimes the region tells you less than you’d think.
