How much money is a good nights rest worth

Is there a dollar amount on what a good nights rest (undisturbed) worth?

Well there's not a set amount, but I'm sure it would vary from person to person. I mean some people like sleeping more than others, some people have a harder time sleeping than others, so if there was a monetary value, it wouldn't be a single value. I personally wouldn't pay a dime because I'm an extraordinarily heavy sleeper and I could fall asleep anywhere.
