I did not see this in the hotel forum and maybe it belongs over there instead of this section. I have been using Welcome rewards and I like the concept when there are no SPG or Hyatt properties at my desired location. For anyone that does not know how it works: Every 10 nights at participating hotels booked via Hotels.com you get a free night. The value of the room is determined from your average spend over the 10 nights. If you want to book a room that is more expensive than your credit, you simply pay the difference.
