Just received my 3 stay/10k bonus offer today ^ ^
For me, this is actually the best promo by far because the target # is so low and the earning period is so long and is the only one that encompasses the holiday period. Even better than the last promo which required 5 nights for the 10k bonus. Hyatt FFNs are - of course - more valuable, but the qualification and redemption periods are severely limited, and the room rates are usually higher.
Makes me feel even better about my decision to get a Marriott Visa card earlier this year.
