I received the following Tweet back from Wyndham when I asked them the question of earning miles vs. points for your stay:
"Hello, regardless of your earning preference if you qualify for the promotion you will receive 16000 points. "
So that is good news. If staying at a Wyndham Resort or Hawthorn hotel you get 500 miles per stay for most airlines, 600 with Southwest. Through September 13 you get 4x points or miles starting with your 2nd stay. If you select Southwest, this means you'll get 2,400 Southwest points, which equals $40 towards Southwest travel.
