Marriott Rewards quietly added on January (read more here) its Las Vegas Autograph Collection Cosmopolitan hotel’s Identity program to points conversion partners.
Now, Marriott has entirely removed all the references to this partner program (Cosmopolitan Identity) from its website here but Marriott Rewards points should be still convertible to Identity points per Cosmopolitan’s website here.
Above is the chart from the Marriott’s website before the change overnight.
I think that program should always give its members heads up if program partners are leaving, so that they could get last redemptions in. Like I said on my post when this program started, I have no idea if converting Marriott Rewards points to Identity ones made any sense.
