If I redeem a certificate for a free night (1-5 summer promotion) at a full service Marriott will I still get free breakfast as a plat?

Normally I don't even eat breakfast but just found out that I am going to take my daughter for one night event in the fall and will need to stay over by by the airport. This is a perfect excuse to burn up a certificate and save a few dollars.

Just wanted to get the details.

Thanks.
