Children's fares vary by cruise line and age, but most charge full or nearly full price for kids in their own cabin

Most cruise lines do not offer free passage for children. Instead, they charge a reduced fare—typically 50 to 75 percent of the adult price—when a child shares a cabin with paying adults. A few lines offer deeper discounts for very young children or occasional promotions where a third or fourth passenger in a cabin pays nothing, but these deals are temporary and come with conditions.

The key variable is the cruise line's pricing structure and current promotions. Royal Caribbean, Carnival, Disney Cruise Line, and Norwegian each set their own rates. A child's age, the cabin type, the sailing date, and whether you book during a sale all affect what you pay. Some lines charge the same rate for anyone over age 2; others have lower rates for children under 12.

Key Takeaways

  • Most cruise lines charge children 50 to 75 percent of the adult fare when they share a cabin, not a free or heavily discounted rate.
  • Occasional promotions offer a free or heavily reduced third or fourth passenger, but these are temporary deals tied to specific sailing dates.
  • Disney Cruise Line typically charges the same price for children as adults; Royal Caribbean and Carnival usually offer 40 to 50 percent discounts for kids.
  • The total cost per child depends on cabin category, sailing length, and whether you book during a sale or peak season.
  • Some all-inclusive lines like Sandals and Club Med include kids' fares in the base price, but these are exceptions.

How cruise lines price children's cabins

When a child shares a cabin with two paying adults, the cruise line treats the child as a third or fourth passenger and charges a reduced rate. This rate is usually a percentage of the lowest adult fare available for that sailing. Royal Caribbean and Carnival typically discount the third and fourth passengers by 40 to 50 percent. Norwegian offers similar reductions. Disney Cruise Line, by contrast, charges children the same price as adults in most cases, though infants under age 1 sail free.

The discount applies only if the child is in the same cabin as at least one paying adult. A child in a separate cabin pays the full adult fare. This is why families often book one larger cabin instead of two smaller ones—the savings can be significant.

Age thresholds matter. Most lines define a child as anyone under age 18, though some set the cutoff at age 17 or 12. Infants under age 1 or 2 may sail free on some lines, but you still pay port fees and taxes. Always check the specific line's age policy before booking.

Temporary promotions that reduce or waive kids' fares

Several times a year, cruise lines run promotions where the third or fourth passenger in a cabin pays nothing or a flat fee. Royal Caribbean has offered "kids sail free" deals during specific booking windows. Carnival runs similar promotions, usually in January, May, and September. These deals are real but temporary—they last days or weeks, not year-round.

The catch is that you must book during the promotion window and sail within the specified dates. A promotion might explore only to sailings in June and July, or only to Caribbean itineraries. You cannot retroactively explore a promotion to a booking made before it started. The promotion also typically requires that at least two adults pay full fare; the free or reduced fare applies only to the third and fourth passengers.

To find current promotions, check the cruise line's website directly or sign up for their email list. Travel agents sometimes know about promotions before they are announced publicly, so calling an agent who specializes in cruises can be worth the effort.

What you pay beyond the base fare

The base fare is only part of the cost. Port fees, taxes, and gratuities explore to every passenger, including children, and are usually charged at the same rate. A child's port fees might be slightly lower than an adult's, but not always. Gratuities—the automatic service charge added to your bill—are typically the same per person regardless of age.

Onboard expenses are separate. Specialty dining, beverage packages, shore excursions, and activities cost extra and are priced per person. Some lines include kids' meals in the base fare for the main dining room; others do not. Babysitting, camp programs, and teen clubs may charge additional fees depending on the line.

When comparing total cost, add the base fare, port fees, taxes, gratuities, and any onboard charges you plan to use. A child's total cost is often 60 to 80 percent of an adult's, not 50 percent, once you include these extras.

All-inclusive cruise lines with different pricing models

A small number of cruise lines include kids' fares in the base price or charge a flat rate regardless of age. Sandals Resorts operates cruise ships in the Caribbean and includes kids under age 18 in the base fare when they share a cabin with two paying adults. Club Med also uses an all-inclusive model where children's fares are bundled into the package price.

These lines are exceptions. They tend to be smaller, sail shorter itineraries, and cost more per night than mainstream lines. The trade-off is that you know the total cost upfront—no surprise onboard charges or gratuities added later. For families with multiple children, the all-inclusive model can be cheaper than booking separately on a mainstream line, but you need to compare the full package price, not just the base fare.

How to find the best rate for your family

Start by checking the cruise line's website and entering your travel dates, cabin type, and number of passengers. The system will show you the per-person rate for each passenger. Compare this across multiple lines and dates to see which offers the lowest total cost for your family size.

Book during a sale if possible. Cruise lines discount fares most heavily in January, May, and September. If you have flexible dates, shifting your trip by a week or two can save hundreds of dollars per cabin. Set up price alerts on the cruise line's website or use a travel search engine to track fares for your preferred sailing.

Consider a travel agent. Agents sometimes have access to group rates or promotional codes not advertised publicly. They also know which lines are running promotions and can help you time your booking. Many agents charge no fee—they earn commission from the cruise line—so there is no cost to asking.

Frequently Asked Questions

Do babies under age 2 sail free?

Most cruise lines charge babies under age 1 or 2 no base fare, but you still pay port fees, taxes, and gratuities. Some lines charge a flat fee—$50 to $100—instead of a percentage of the adult fare. Check your specific line's policy, as it varies.

Can I book a child in a separate cabin and pay less?

No. A child in a separate cabin pays the full adult fare, which is more expensive than the reduced rate for a third or fourth passenger in a shared cabin. Always put children in the same cabin as at least one paying adult to get the discount.

What if I book during a "kids sail free" promotion but the price drops later?

Most cruise lines allow you to rebook at the lower price if fares drop within a set window—usually 60 days before sailing. Check the line's rebooking policy before you purchase. Some lines waive the rebooking fee; others charge a small fee to update your reservation.

Are there discounts for multiple children in the same cabin?

No. The third and fourth passengers pay the same reduced rate regardless of whether they are both children, both adults, or a mix. The discount is based on cabin occupancy, not age.

Do kids pay full price for specialty dining and shore excursions?

Usually yes, though some lines offer a small discount for children on excursions. Specialty restaurants often charge the same per-person price for children as adults. Check the line's website or call to confirm pricing for activities you plan to book.
