Sorry for the thread revival but I just found/remembered an interest twist in all of this. When I was first flying with United, I never belonged to any hotel program/didn't realize I could get night stay credits for direct billed airline employee stays.
When I returned from furlough, I used my membership number at a couple of Marriotts and Starwoods. While Marriott didn't give me any night credit or points, they did give me lounge access. Starwood, on the other hand, gave me a night stay credit at the hotel that I stayed and charged dinner.

I have already double checked all of my hotel memberships and have a list of my membership numbers. I will have to see how often I'm able to get night stay credits with each hotel chain.
I currently have membership with Marriott, Hyatt, Starwood, Hilton, Priority Club, Club Carlson, Best Western. It'll be interesting to see which ones give me night stay credits - I understand that Hilton and possibly Hyatt and Starwood will give me night credits. I'm not sure on Priority Club or Club Carlson. I don't think we stay at Best Westerns and I can get a no questions asked status match anyway.
