Identity, the Cosmo’s loyalty program, sent another set of $99/night with resort fee offers out via email. We stayed at the end of June on an earlier one and a few days before our stay added another night, that extension was the free Identity night that comes with their silver status for the Friday night.
As is normal, in my experience, I had to file a missing stay twice for the two folios (one for promo rate nights and one for the free night) I received two approvals and all the nights and spend that earns Bonvoy points showed in Marriott account totals and activity.
