The reason we did not get ours at MK this year was mainly because a lady and her son were standing so close to us that is seemed they were with us! The other shot has DD holding tinkerbell and is a closer up shot (with less background people) but the photographer had her hand so far out, you couldn't even see Tink. So get them done on one of your first days so you can have it retaken if it's not good. We did get DD in front of the Tree of Life holding Simba (one of her favorites!) the one of all of us was good except I forgot to remove my sunglasses! There you only see the tree and the people in the photo.
Lasy year we had one done at Epcot, there they put your photo in front of the castle with Mickey & Friends surrounding you.
