Kids Sail Free Cruises
Kids sail free offers are real but conditional: MSC runs the closest thing to a standing policy for under-12s, Royal Caribbean and Norwegian open kids-sail-free windows several times a year, and every version still charges taxes, fees and gratuities for the child, typically $120 to $200. Timed right, a family saves $400 to $900 per sailing.

Check datesThe fine print that decides whether it is real
- Free means the cruise fare only: the child's taxes, port fees and gratuities ($120 to $200 on a week) always bill. A real offer still saves hundreds, just not everything.
- Kids occupy the 3rd and 4th berths of the cabin: two adults paying full fare is the entry condition everywhere.
- MSC: the most consistent, under-12s free or nearly free on a wide swath of sailings year round, which is a core reason MSC wins the family value war.
- Royal Caribbean: kids-sail-free windows around Wave Season, back-to-school and Black Friday, excluding school holiday departures, naturally.
- Norwegian: bundles it into Free at Sea promotions as free 3rd and 4th guests, on and off through the year.
- Carnival and Disney: essentially never. Carnival prices kids cheap instead; Disney prices kids like adults who eat more.
Stacking it into a genuinely cheap family week
The maximum-value pattern: an MSC or promo-window Royal Caribbean sailing, from a drive-to port so there is no airfare, in late August or early December when adult fares bottom out too. A family of four can clear a 7 night Caribbean week under $1,900 all-in that way, which is theme-park-weekend money for seven days of food, pools and childcare. Our family cruise guide ranks which line fits which ages once the price question is settled.

Frequently asked questions
Which cruise line has kids sail free right now?
MSC most consistently. Royal Caribbean and Norwegian windows open and close through the year, and our desk tracks them live: call and we will check every line for your dates. Prices checked: August 2026.
What ages count as kids for kids-sail-free?
Usually under 12 at MSC and under 12 or 17 depending on the promotion elsewhere. The age at sailing date, not booking date, is what counts.
Is kids-sail-free better than just booking the cheapest line?
Run both numbers: Carnival's low kid fares sometimes beat a competitor's free-kid offer once cabin categories match. The two-minute version of that math is exactly what our phone desk does.
