Hi,
Go and have fun with it. My sister and I went in December and we are both in our twenties, we did a bunch of character meals. I thought I would feel funny talking to the characters, as I am usually shy, and thought it would be embarrasing. But once the characters came, I felt like a little kid again. Eeyore liked my shirt because he was on it and pointed to my sister and was like where's yours?. Belle even said, it's nice to see the big kids having fun. Also, Goofy was funny, we were at Liberty Tree Tavern, and we were in the corner and he came up next to me. He surprised and I said you scared me, and he gestured, like no, not me. Have fun on your trip.
