My 8 year old granddaughter was allowed to "self-check", on our Thanksgiving cruises this year. Daughter laid down the law with her, before allowing it. She always had a wave phone and HAD to let someone know when she was leaving. She was only allowed to go wherever her parents were at the time. NO running around the ship.
I don't know what the "rule" is, but on our cruise earlier this year on the Wonder, 7 year-olds were able to have check-out privileges with parental permission.
