This property was
bookable at 10k per night, and was classified as cat 2 before the changes.
Once a property is bookable, isn't the category of the property fixed?

Will write in to hilton and see what they say.
I agree that they have kept their (award) reservations process shady. First was the disappearance of all standard rooms, then it came back briefly and now all standard rooms redemption amount doubled. And all these before they even had a single guest actually staying with them. Whoever the GM is, your pre-opening act is priceless..
