$20 per adult to a max of 2 adults (i.e. $40) per room credit against breakfast in Motif restaurant.

This is in lieu of the 500 SPG point amenity.

Will find out in the morning if they just apply a $40 credit to the bill, or if they apply "up to $20" for whatever the 2 adults ordered, as we have a child in our party...

UPDATE: They applied a $40 credit to the bill each meal. You just present the amenity card you get at check-in, complete the tip on the full bill, and they subtract $40 off it when it is posted.
