Hi
bsb21,
For participating hotels without a Lounge or if the Lounge is closed, you are entitled to receive a free Healthy Start Breakfast, Monday through Friday. Hotels are not required to provide free breakfast on the weekends, but many do. I hope that answers your question.

EDIT:
BruceWG is also correct.
Best regards,
