It would be nice if Hilton published a one-month notice when making changes to the caps. That would be transparent on their part and allow us opportunity to book if we really wanted something at any of those locations.
I recently dumped a lot a lot of my points balance into reservations for 20 free nights at a couple properties where I suspect the redemption rate will go up. May as well lock in the value while I can. If my plans ultimately change I can always get the points refunded.
