I have only been to Chef Mickey's so I can only comment on that. This past January my group of friends and I went. We range in age from 18 to 21 (me being the oldest). And we had an awesome time. I can't wait to go back in October. Everytime I go down, I make sure to go to at least one character breakfast. I just got my pictures back the other day (I know, it's like 5 months later), and when I look at them I can still remember how much fun we had that morning. I'm sure your oldest will enjoy, because even if he or she doesn't enjoy the characters, the food is really good.
