When we went last November, they just took a picture of me and our two girls together. I had expected them to take a picture with Minnie, but they didn't. The photo was taken on the front porch, under the cover with me and the girls against the little fence (sorry for the wrong terminology, but hopefully it will make sense). There were other people standing in line to get to the check-in podium in the background.
We didn't buy the picture.
