Hilton HHonors members must first register at HHonors.com/More prior to check-out of your stay within the Promotion Period. Registered HHonors members will receive the bonus only for nights completed during the Promotion Period, regardless of a check-in date before the Promotion Period begins or a check-out date after the Promotion Period ends. For the More Nights More Points promotion, registered members will earn Double Points on stays of two (2) consecutive nights, Triple Points on stays of three (3) consecutive nights, and Quadruple Points on stays of four (4) or more consecutive nights during the promotion period. “Double Points” means you will receive a bonus equal to the number of Base Points earned during a stay. “Triple Points” means you will receive a bonus equal to double the number of Base Points earned during a stay. “Quadruple Points” means you will receive Bonus Points of three times the number of Base Points earned during an eligible stay. Bonus Points earned on Base Points do not count toward tier qualification. Please allow six to eight weeks from completion of your stay for points to appear in your HHonors account.
