Hyatt normally is not stingy but FFN has become way too popular so the awards around that timeframe is harder to find, especially at the end when everyone is trying to use them up. Local ORD folks with unused FFN probably consider PH as their prime target.
Also a bunch of folk
hoard awards and cancel at the last minute so you may have a chance there.
I hope hyatt will use different buckets for FFN and regular awards in the future; after all there is a difference between spending 18000 pt of true loyalty points and $120 from two night at HP by someone who never cares about Hyatt.
Also I would strongly favor a more restrictive cancellation policy perhaps two weeks on FFN but keep the existing one for points.
