I'm in the middle of a 12 night stay at a Park Hyatt all on points booked 3 days before arriving. In areas I frequent, free nights are widely available.

In a couple of properties, nothing seemed available for months on end - free nights or standard suites. I called my concierge and magically free nights opened and standard suites in most properties.

In the 1 that refused to open free nights, my concierge apologized and gave me free points as an apology. I know Hyatt corporate does crackdown and push for properties to adhere to program terms for sure but thay some properties need a stick
