Do the bonus levels have infinite waves or is there a large reward at the end?

Question

I have played through two of these extra levels, but left them until I started playing on Hero difficulty. Because of this, it is quite hard to survive for too many rounds. So I wanted to ask, do these bonus levels have infinite waves or not? And, before I take the time to try to beat these levels, is there a big pay out at the end?
