Overnight French Toast

I found this in a recent issue of Binah Magazine, and, while I haven't made it yet, it looks like a great make-ahead for a busy family morning, or for a celebratory brunch. I did not include the overnight time in the refrigerator in the time estimates for making this recipe.
