Update 3/25/20: If your certificate is expiring within 30 days Marriott will actually extend it for one full year. This can be done via chat but might be YMMV. Hat tip to me_frugal.
According to an e-mail seen by Loyalty Lobby Marriott will extend free night certificates until January 31st, 2021. Normally these certificates are given out to credit cardholders and are valid for ~ 12 months after they are issued. Apparently the extension will take place sometime in April. I’ll believe it when Marriott actually extends the certificates, given Marriott’s track record.
