Seems odd, but I'd blame it on the property. Gold should get you CL without asking. Lots of stays in a given hotel usually more so.

If you have the bookable nights and are interested, Hyatt is running a double-stay credit deal (not double-night credit) till the end of March. 13 stays is now worth 26 and gets you Diamond. I would have said Marriott was more consistent, but Hyatt has better resort deals and the FFN thing is the mother of all promos.
