As I mentioned in another thread...
<-- see where it says "HH: DIA" in my programs, next year it will say "HH: Nada".
This devaluation validates the decision that I made last year not to patronize Hilton anymore even though I've been HH Diamond for a number of years. It comes down to unimaginative top-tier benefits vis-a-vis the other programs (specifically compared to Starwood and Hyatt) and the lack of loyalty incentives aka promos. Thus, my projected number of stays this year is 4, and only because of the current 25,000 points promo. This was just enough points to top up my HHonors account for a nice Hilton vacation before I lose my status.
I follow what some posters here are saying that devaluation happens to all programs. Hilton has not been the lesser of the evils.
