Hilton HHonors members can earn up to quadruple points on hotel stays through the More Nights, More Points promotion running through Jan. 31, 2014.
Members who register for the promotion and stay at participating hotels can earn double points on stays of two consecutive nights, triple points on stays of three consecutive nights and quadruple points on stays of four or more consecutive nights.
Registration is required at http://www.HHonors.com/more prior to checkout.
Not all hotels are participating in the promotion—check the list of non-participating hotels at http://www.insideflyer.com/link/?9822
One-night stays will earn the standard points and are not eligible for the bonus. The bonus only applies to base points earned, so points and miles members will earn the same number of bonus points as points and points earners.
