Random non restaurant data point: Have a FHR room booked at Loews Ventana Canyon in Tucson AZ. Room was $280 plus $40 due at checkin. So I have $20 left of the $300 FHR credit, so I wondered if I prepaid the $40 due at checkin, if it would trigger the last $20 of my FHR benefit. So I prepay the $40, and it actually credits my Resy credit instead. There's no Resy restaurants at the hotel or in Tucson, but maybe there's one at a Loews hotel somewhere so any charge from them hits it?

Just thought that was interesting. Still haven't figured out how to get the last $20 out of my FHR money.

Edit: Also I've received the Resy credit at Kona Grill (Desert ridge) in Phoenix, not sure how the pinned master list gets updated but someone could add that.
