Was there some change in Hyatt policy regarding free night awards since April? I have been told on countless occasions today that hotels allocate a specific number of rooms for points and another set of room for award certificates, shouldn't they be the same?

I had to move some dates around for a booking at Hyatt Centric Waikiki (one of those Hyatts that plays games with min night requirements for award bookings) and it took me messages on FB, messages on twitter, and finally a few calls to get it booked using 2 certificates and remaining nights on points. I didn't have any issues when I booked back in April. Now I am trying to switch one of the nights from a point booking to a gifted certificate and even though I was told to have the gifter call to give permission for the certificate to be used, Hyatt won't allow it. What gives? I escalated this to a supervisor on the globalist line and got the same spiel about the room allocations for points vs certs. She can't pull up a single standard award night and so she says the certificate can't be used. Any advice? Should I just HUCA until I get a competent agent?
