Not personally but I see alot of others doing it each time we go to one! The characters will come by and spend as much time with you as kids if they get the feeling you want them to. If not, they'll say a quick hi and move on. I see adults getting autographs and pictures at both character meals and the parks. My husband's cousin and his fiancee went in September without kids and had a ball. I told them they had to try at least one character meal and they had way more fun than they thought they would. They had a picture of themself and Mickey on their Chrismtas card!
