In July this year, Hilton Hhonors announced its Unlimited Bonus promotion for stays till 31 August 2016, which offered 2x points at all properties. No exclusions. This was largely the same as the Double your HHonors promotion for the first quarter of 2016 - the only difference being that the Q1 promotion offered a choice of points or miles.
Now, the promotion through the rest of this calendar year has been announced, and it will also be a 2x points promotion at all Hilton HHonors properties, with no exclusions.
