These benefits are great for the HHonors system. They are now more comparable with SPG's benefits, which is great! I always use Cash & Miles for SPG which stretches my SPG points, it is also such a better value then using an all point award too.
I just got off the phone with Hilton Honors and inquired about these benefits. The women was surprised that I had heard of these award opportunities since they have not been published yet, but went ahead to give me more detail anyways. She said they are having some system issues, but likely they will be available April 7th.
I wrote more about the benefits and enhancements on my travel blog site:
