Buried in the
T&C update of 19 July is this sentence:
Guaranteed reservations availability, subject to the restrictions stated herein, at hotels within the Hilton Worldwide portfolio when paid reservations are made before midnight hotel local time, two or more days (48 hours) prior to intended arrival. RESTRICTIONS: This guarantee does not apply to reservations paid for in part or in full by HHonors points, free night certificates issued by Hilton Worldwide.
While this had already been effectively removed by the premium room reward nonsense at a number of highly desirable properties, it seems to me to be yet another way our Hilton points are being devalued.
