Bonus Bucks (BBs) are just another word for gift certificates that are used at certain Marriott-related hotels that can help reduce the cost of your stay. Think of them also as coupons off the price of your hotel bill. They are treated as cash though.

Usually BBs are issued only when staying at certain Marriott hotels on weekends. When you book your room, you would use the M11 code. Just be sure when you originally book a stay, that you put the code in and check to see if your desired stay comes up as an available rate.

This code, which is based upon availability, would entitle you to receive a $50BB when staying on a Friday or Saturday night or a $100 BB when staying two nights in which one night must be a weekend night. For example, you could book a Thursday/Friday night stay or a Friday/Saturday night stay.

Usually upon checkin or at checkout, the hotel is supposed to issue the BB to you. You can use it on a future 2-night stay.

Hope this helps.
