I'm single, with no kids (unless you count my cat, but I can't take her into the parks), and I LOVE meeting the characters! Matter of fact, the first time mein sister and I went to Disney World without our parents (she was 25, and I was 24 at the time), she wanted a picture of her with Mickey and Minnie. I don't remember the reason why we never wanted to do it as kids. Either lack of interest, or we wanted to spend more time on the rides. One of my favorite Disney moments was in 2009 during the Christmas party (I forgot what it was called!) was getting to meet Scrooge McDuck. We've never done a character meal, though. I don't know if mein sister will go for it, and I also don't know if they'd accept a reservation for one.
Love Me, Love My Cat
