Average price per person, per night for 2 adults sharing a interior cabin. Each sailing counts once. Only fresh, available USD quotes are included; this compares departure months, not a forecast. Budget, trip length and quick filters apply to the sailing list below, not the monthly averages.
Lowest average in this year: Dec 2026 · $137 per person/night across 3 sailings. Months with fewer than three sailings are not compared in this summary.
Worth a closer look
Fresh tracked fares across all departure dates, matching your guests, cabin, port, budget and trip length.
The current cabin-class total is at or below the lowest total in our recorded history for that sailing and guest count, and a higher price was previously recorded. It is not a claim about every fare ever sold. Specific categories, guarantees, promotions and inclusions can change; check the sailing page before booking.

Planning your Mariner of the Seas cruise
What is the cheapest current cruise?
The lowest fresh cabin total currently captured for two adults is $618. Choose a cabin class above and sort by lowest cabin total. Confirm the category, taxes, extras and final price before booking.
Which month costs less?
Use the monthly chart to compare the same cabin class and guest count. The table includes the average, median and lowest nightly fare, plus the number of sailings. A month with one sailing is not enough evidence of a seasonal trend.
Can I track a cruise I already booked?
Yes. Open your sailing and choose “Already booked?” to save your cabin and booked price. A lower observed fare may be worth a call to your travel advisor, but repricing depends on the fare rules. View your tracked cruises or read the price-drop guide.
Are deck plans a list of cabins available to book?
No. A deck plan shows the ship layout. Live room availability and guarantee assignments are separate. Check that the plan’s dates cover your departure before choosing a stateroom.
