I was surprised recently when I had either a Priceline or Hotwire Opaque stay award me stay and night credits. This has not happened in 10+ years. I called and asked to have the reservation attached to my Honors because I wanted to use Digital Key (which I was able to use). I didn't attempt to use any on property benefits because I didn't think I had any on an Opaque stay, but was given water at check in. I am awaiting the letter from Hilton telling me to book direct in the future.
