I've heard it be said that some properties will allow you to reserve higher end rooms with points, for a premium. So if the property is 25,000 for a night, you could get a suite for 30,000 or 35,000

But after months of looking, I've yet to find a single property anywhere that allows this.

At this moment I'm starting to assume I was misinformed, but I thought I would come ask the experts.
