Hilton is starting 2016 with a double points promotion that will run from January 1 through April 30, 2016. With this offer you can select to earn either double bonus HHonors points or double airline miles (from a participating airline). Unfortunately though, once you pick your bonus, you cannot change it from one stay to another. Typically, the bonus HHonor points seems to be what the majority of people select. However, if you typically have inexpensive one night stays, the double airline promotion might be your best choice.
Fortunately, there are no excluded hotels for this promotion. However, you will need to register PRIOR to checking out from your hotel stay.
An Extra Bonus…
Now, if you have their co-branded credit card, you’ll get an extra 1,000 points when you use your respective card during your first stay during the promotional timeframe.
