The Kids Sail Free is limited to triple, quad, and family occupancy staterooms/bookings, the pricing will not show unless there is a guest 12 or younger in the same reservation with at least two other guests. Taxes, fees, and port expenses are additional and apply to all guests.

Under Royal Caribbean's popular "Kids Sail Free" promotions in 2026, typically up to two children (aged 12 and under) can sail for $0 cruise fare when they are the 3rd and 4th guests in a stateroom with two full-fare paying adults. This means a family of four can often sail for the price of two, plus the cost of taxes, fees, and port expenses for the children. It is important to note that this is a promotional offer and is not available year-round; it usually excludes peak holiday periods such as Thanksgiving, Christmas, New Year's, and Spring Break. Additionally, while the "cruise fare" is free, you are still responsible for the kids' gratuities and any onboard spending. In 2026, Royal Caribbean has also introduced "Free 3rd and 4th Guest" offers that occasionally extend to older children or adults on select sailings. To maximize these savings, you generally need to book at least 6 to 9 months in advance, as the cabins that accommodate four people (staterooms with sofa beds or pull-man beds) are the first to sell out during these massive sales events.
