The Best Day to Book a Cruise Is Saturday. Here's Why.

The best day to book a cruise is Saturday. You're 4.5× more likely to catch a real price drop compared to Monday, based on 2.6 million price snapshots across 9 cruise lines.

We track more than 35,000 sailings every week, and once we graphed all of that activity, the pattern was hard to miss. Saturday consistently delivered the strongest odds of a real price drop — even across different cruise lines, regions, and fare types.

This analysis is based on 2.6 million price snapshots collected across 9 cruise lines and 75+ ships. Cruise lines adjust fares algorithmically now, and the weekend keeps coming out ahead.

This guide breaks down those patterns:

• The weekly pricing rhythm cruise lines follow
• The days they adjust fares
• When last-minute discounts actually happen
• How far out the average traveler should book

Key Findings at a Glance

Best Day of the Week to Book a Cruise

The weekday trend was the biggest surprise. Older studies always leaned mid-week — but that isn't how modern cruise pricing behaves anymore.

What the Numbers Show

Saturday takes the crown.

• A 10.8% chance of catching a 5%+ price drop.
• It's also the only day where prices fall on average.

Friday sits right behind it at 9.4%, making the weekend the strongest 48-hour window for real discounts.

After that, the curve drops quickly:

• Thursday: 5.6%
• Tuesday & Wednesday: around 4%
• Sunday: 2.7%
• Monday: 2.4% (the weakest day of the week)

If you're checking once a week, Saturday gives you the best odds — roughly 4.5x better than Monday. For more on how price drops vary by cruise line, the patterns diverge more than you'd expect.

When we first saw these results, we ran the analysis multiple times throughout the week just to be sure. Saturday kept coming out on top across almost every cruise line, even the ones that normally behave differently from the pack.

Best Day by Cruise Line

Once we broke the data out by cruise line, the patterns became even clearer — and in a few cases, completely flipped. Some lines cluster around the weekend, others spike mid-week, and a couple behave in ways that don't match the usual travel-blog tips at all.

Royal Caribbean & Celebrity — Big Weekend Movers

These two lines light up the chart.

• Saturday dominates, with drop rates hitting the 20–23% range — way above normal.
• Fridays are strong too, but Saturday is the real standout.

Royal Caribbean is the second-most volatile major cruise line we track — 27.8% of RC sailings show a 10%+ price swing in any given week. If you sail Royal or Celebrity and you're deal-hunting, Saturday is the window to watch.

Princess & Virgin — Friday–Saturday Split

Both cruise lines show a steady weekend pattern.

• Friday: noticeable bump
• Saturday: often just as strong
• Sun–Wed: mostly quiet

It's not as dramatic as Royal/Celebrity, but the weekend window still matters.

Carnival & Norwegian — Thursday Outliers

These two break from the weekend trend.

• Carnival and NCL peak on Thursday, with drop rates around 6%.
• Friday and Saturday aren't bad — they just don't stand out the same way.

If you're sailing either one, checking fares on Thursdays gives you the best shot at a cheaper cabin.

MSC — Friday Leaning, Not Weekend Heavy

MSC doesn't have a huge spike, but Friday comes out ahead. It's a more balanced pattern overall, with smaller swings compared to the big U.S. lines.

When to Check, by Line

Each line follows its own pricing rhythm — but the end of the week is where most of the action is.

When Cruise Lines Discount Across the Full Booking Window

This is the dataset I check the most often. Booking windows tell you far more about pricing behavior than any sale banner or promo name ever will.

We mapped 2.6 million price observations across the entire booking curve — from nearly a year out to the final days before sailing. Once the data was laid out, the pattern was obvious.

0–50 Days: The Strongest Window for Price Drops

This is where discount activity spikes the hardest. A full 33% of all price drops happen inside this window. Drops average 19.5–25.5% when they occur, though cabin selection narrows.

If the ship still has open cabins, this is the zone where prices move the most. Late shoppers have the best shot at seeing a meaningful drop.

The steep curve matches what we see every week when sailings hit their final payment deadlines. A fare can sit unchanged for months, then drop quickly once cancelled cabins return to inventory.

For reference, Royal Caribbean's final payment is typically due 75–90 days before sailing (and 120 days for longer itineraries), which often lines up with these late adjustments.

51–100 Days: The Second-Best Window

Stronger than expected — and far more active than most "booking strategies" online suggest. This window accounts for 24% of all price drops across the industry.

If you want a blend of cabin options and price movement, this is the range to watch. It's also the window where rebook policies give you the most flexibility — you're typically still before final payment.

101–150 Days: A Quiet Middle With Two Exceptions

Overall, the curve tapers off here (17% of all drops). But two lines behave differently:

This range favors a couple of premium brands, but not the industry as a whole.

150–250 Days: Mostly Quiet

This is the point where discount activity becomes thin.

Once you're past the 150-day mark, deals become the exception, not the norm.

250+ Days: The Lowest Deal Probability

Across almost every line, this is the quietest part of the pricing curve:

"Book a year out for the lowest price" — The data shows the opposite. Long-range booking has the fewest real price drops.

Booking early still makes sense if you care about the exact cabin you want. But low prices? They show up much later in the cycle.

How to Use This

Early = certainty. Late = volatility. Middle = best of both.

Best Months to Book a Cruise — Patterns That Hold Up

Monthly patterns shift every year, but the demand waves stay surprisingly consistent. Growing demand doesn't slow down pricing. CLIA's 2025 industry report shows passenger volume rising past 34.6 million and forecasted to hit 42 million by 2028, which explains why peak months rarely see price drops anymore.

January–March (Wave Season)

The cruise industry's biggest annual marketing push — reduced deposits, drink bundles, kids-sail-free promos. But the base fares themselves? Actually 5.7% higher during Wave Season than outside it. Only Carnival (-3.7%) and MSC (-5.9%) consistently price lower. Strong value from bundled perks, even if fares don't bottom out.

Late November (Black Friday → Travel Tuesday)

Heavy promo stacking: upgrades, OBC, add-ons. High value, but fares don't always drop.

April–May / September–October (Shoulder Months)

Lower occupancy as families return to school. Better Med/Europe pricing, softer Caribbean fares. We saw this firsthand — prices loosened almost immediately.

June–August / Holiday Weeks

High demand, firm pricing. Few real drops — book early and reprice.

Last-Minute Deals — When Waiting Helps and When It Doesn't

Some swear by last-minute deals, others say they never happen. The truth sits in the middle — and you can tell which way a sailing is leaning once you know what to look for.

When Waiting Can Save You Money

The ship still has space. If a sailing is close to departure and still has a good number of cabins available, prices often soften inside 50 days.

How to check availability:

• Look for multiple cabin types still open
• Click into a category and check for lots of deck options
• Try searching for 3–5 guests — if it still shows plenty of cabins, there's room

Shoulder-season trips. Caribbean in September or early December. Mediterranean in April or October. Alaska in May.

You don't care about the exact cabin. If you're not attached to a balcony or specific deck, waiting becomes easier.

Repositioning cruises. These often drop late because they appeal to a smaller audience.

Pro pattern I watch: If a fare moves every few days inside the last 40–50 days, the cruise line is actively adjusting. Understanding cruise price history for a specific ship tells you whether a sailing is likely to keep moving.

---

When Waiting Usually Backfires

Summer and holiday weeks. These fill early. Prices rarely drop.

New ships or "hot" itineraries. These almost never discount late.

Alaska in peak season. June–August sells out early, especially balconies.

You need flights. Airfare can wipe out any cruise savings.

Last-minute deals aren't random. They follow patterns. Once you understand them, waiting stops being a gamble and becomes a strategy.

How We Track Prices

Every week, we track more than 35,000 sailings. Each sailing generates multiple price snapshots, and we compare every new price against its recent average to see when something meaningful changes.

We use a 90-day trailing average because it filters out the noise. Cruise pricing wiggles constantly — a long window gives a much cleaner signal.

A real drop isn't a sale banner. It's a price that falls 5% or more below its 90-day trailing average.

Looking at prices this way shows:

• When cabins actually get cheaper
• How often lines adjust fares
• Which days real drops appear
• How pricing behaves across the booking window

This isn't guesswork. It's what we see across 2.6 million price snapshots every week. You can explore current deals to see this in action, or install our Cruise Price Tracker to see price history on any sailing.

The Bottom Line

Cruise pricing looks complicated from the outside, but the rhythms are consistent. Once you understand the weekly cycle and the booking windows where prices move, everything gets easier.

• Check prices on Saturdays
• Watch the 31–100 day window for the best mix of price and cabin choice
• Don't rely on 150+ days for deals
• Reprice if you book early — we compare the best cruise price trackers to help you choose

Most travelers book blindly. You don't have to.

With the data behind you — and a little timing — you can book confidently, skip the guesswork, and know you're getting a fair price without waiting for a miracle sale.

Cruise Radar scores every fare 0-100 based on 2.6M+ price snapshots, then shows you the score right on the booking page — so you know whether a price is actually good before you commit.
