I find Hilton to be the worst value of all my frequent traveler accounts. I try to never let my account get too high as my Hilton points seem to devalue quicker than the others. I am at about 120k right now. I often will just do a cash and points to take the edge off of stays. I typically see about .003 to .004 cents per point. These are mostly one night bookings though so not as good as value as 5th night free bookings but even then, the value just isnt there compared to other programs. Too bad too, as I am now lifetime Diamond.
