Starting today, you can earn 2,000 bonus Hilton points for every stay. This promotion runs February 1 through April 30, 2017. You can take advantage of this promo on every single stay as there is no cap or minimum number of nights you must stay to qualify. While only paid stays qualify, if you have any extra incidental charges on a reservation made with points, that should trigger the bonus.
You MUST register for this promotion PRIOR to checking out of the hotel. You can register here. While this is not a promotion that will make me change any stays to a Hilton property, it is great for those who will be staying at a Hilton anyways over the next 3 months.
