Sorry if this has been asked before, but searching this thread didn't yield an answer.

If I am staying on a points+cash upgrade award stay, does that qualify as a paid nights toward my 25 night megabonus? The upgrade charge of $100 per night is more than I've paid for several of my other qualifying nights, but technically the base rate is still an award stay, which would be excluded.

Has anyone gotten promo credit on a points+cash stay before?
