The no-notice devaluations are an unfortunate (and inexcusable) Hilton hallmark, and one of the reasons it's my third program (after Marriott and Hyatt). It's been a difficult program for finding good redemption values for several years now, and that is clearly going to be even more true going forward.

IMO the outrage here is fully warranted, particularly from those who've acquired their points the hard way (i.e., through stays).

If you want to send a message to Hilton, cancel your credit cards.
