Re the Destination residences, I noticed that the Work From Hyatt page has been updated as follows:

• Workspace that’s either a separate, private space or a complimentary second guestroom (at Destination Residences, workspace is living space within your residence).

OTOH, the GH PDC use of the club lounge would only count if it it is dedicated to one guest. So maybe if two people book it they assign the next one a meeting room?

I've booked a WFH rate at the GH PDC for December, so would be interested in any updates on WFH experiences there, or at the nearby Andaz or Thompson Beach House.
