Yes, every child on a Disney Cruise receives their own Key to the World (KTTW) card in 2026. This card serves as their ID and their room key. A supportive peer "parenting" detail: parents have the option to "lock" or "enable" charging privileges for their children’s cards. Most parents keep the charging disabled to prevent accidental $500 arcade sprees. Additionally, kids aged 3–12 who are registered for the Oceaneer Club or Lab will receive a Disney Cruise Line "Mickey Band" (similar to a MagicBand). This band is used for secure check-in and check-out and for the counselors to track where the child is in the club. While the band is for the kids' clubs, the KTTW card is still necessary for getting on and off the ship at ports like Castaway Cay. In 2026, many families use lanyards to help kids keep track of their cards so they don't get lost in the "stateroom shuffle."
