1. Free night certs expire.
2. You can't pay additional points to redeem them at a higher category property or for an upgraded room.
3. With free night certs, you lose the fifth night free feature of award bookings with points. So when you compare this offer to points, if you can arrange your award stays to take advantage of the fifth night free, you need to adjust for the points needed for 3/4 of an additional night.
