This year we are going during the Food and Wine Festival, so I'm not sure we'd have snack credits left....if we do, we'll be buying some of the Mickey Mouse Rice Crispy Treats to take home to our cat sitter.
If we have CS left, the morning before we leave we'll find a family that fits our CS's and help them out. I agree, why waste the credits? Hopefully, it'll help spread the pixie dust onto that family to pass onto another!
