Marriott Rewards launched the Experiences Marketplace earlier this year (carbon copy of SPG Moments) but with fixed price listings only.
Now Marriott Rewards has allowed bidding on some of the experiences and has been sending out emails to some members about this initiative.
You can access Marriott Rewards Experiences Marketplace here.

The number of events that are available for bidding is rather low (and not that many fixed price ones either). These (only) make sense if you have way more Marriott Rewards points that you can ever plan to use. Better to get some value out of them, right?
