I wish there was an answer to this question, but there isn't. They rotate princesses & other female characters each day & meal. A couple of years ago, the characters we saw at Akerhaus for any meal were all princesses. Back then, odds were good of getting to see Snow White. Now they've added Jane, Alice, Mary Poppins, etc. Your odds are even lower. I do think the breakfast and lunch at Cinderella's castle are still prirncesses. That might make it easier. I've also seen Snow White in Germany in Epcot, so maybe your daughter could settle for a meeting, autogaph and a photo. You can check with guest services each morning when you enter the partk, they should be able to tell you where you might see her that day. Best of luck!!
