Lightly butter a 3-quart baking pan. Cover the bottom of the pan with half the bread slices.
In a medium bowl combine 6 of the eggs with all the half and half, 1 cup of sugar and 2 teaspoons of vanilla. Pour half the egg mixture over the bread. In a separate bowl whisk the cream cheese, remaining 2 eggs, teaspoon of vanilla, and 1/2 cups of sugar until smooth and creamy.
Spread the cream cheese mixture over the bread layer. Arrange the rest of the bread over the filling and top with the remaining egg mixture. Sprinkle with nutmeg. Cover and refrigerate overnight.
Bake in preheated 350 degrees F oven for 60 minutes.
Let stand 10 minutes before cutting. Serve with warmed maple syrup if desired.
