When I worked, we used to have to often change room types from rooms with 1 queen bed to a room with 2 full XL beds (full XL is 6 inches narrower than a queen).

Of course, technically, this would modify a guest’s reservation and give them an inferior bed than the one they reserved, so we would go down the list of people who had reserved a room with 1 queen bed and ask if they were willing to change to a room with 2 full XL size beds, and as a thank you, offered a few thousand points.

Obviously, all the single business travelers had no problem accepting a couple extra thousand points for a bed that was 6 less inches wide, but if they did not have a good phone number on the reservation, they were not offered.
