I have twin 9 yo's. DS looks about 9, maybe older. DD looks 6. Never have a problem. We are going near their birthdays and aren't worried. Once you check in the KTTKC states the ages of the children, so if they want my son to order off the adult's menu, he would, but I don't think it will come up. Again, we pre-paid for the plan, so if they want to make him older, so be it!
