In 2026, Royal Caribbean's policy for "free" kids primarily applies to the Adventure Ocean® Youth Program, which is complimentary for children aged 3 to 17. This includes supervised activities, themed parties, and educational games. However, for the youngest travelers (the "Royal Babies & Tots" program for ages 6 to 36 months), there is typically an hourly fee (approximately $8–$12 per hour) for nursery drop-off services. Regarding the actual cruise fare, Royal Caribbean frequently runs "Kids Sail Free" promotions in 2026, where children aged 12 and under can sail for $0 (plus taxes and port fees) as the third or fourth guest in a cabin with two paying adults. It is important to note that even if the fare or kids' club is "free," you are still responsible for the daily gratuities (service charges) for the child, which in 2026 average around $18–$20 per day. Additionally, some "premium" activities like the 3D theater or certain arcade games may still carry an extra cost regardless of age.
