9 year olds and the DDP

[Disneyserver]

My son is 9 so is on the kids DDP. I've noticed his tastes are starting to change and often no longer wants to order off of a children's menu at home. This is our first trip to Disney and our first DDP experience - is he going to be happy with the choices on the kids menus? Are there many restaurants that do not offer kids menus so therefore he could order whatever he wanted? Can I give him my appetizer? Any suggestions would be appreciated. Still in the beginning stages of planning meals and am overwhelmed. By the way - can't find what ADP means but see it everywhere!
Thanks!

Just make him 10 and pay for his adult meal plan , thats what loads of people do, The say there child is 10
