Members earn double points and those that pay using a Hilton affiliated credit cards triple. There does, however, appear to be an issue to get bonus points posted correctly based on my own experiences.
You can access Hilton’s page Power Up-promo here.
The issue with this offer appears to be that the payment card information is not correctly transferred to Hilton (not sure if hotels in some jurisdiction are even allowed to do this due to privacy issues/legislation) from the property and hence the triple bonus points are not posted but rather double.
You then need to contact Hilton Honors and do three/four email rounds before the missing points are posted.
I almost knew when Hilton Honors announced this promotion that there would be an issue to get the credit card related bonus points correctly posted. I doubted that the entire card information that was used to pay for the stay is transferred to Hilton.
Hilton Honors will post the stays but you need to do the usual email rounds. At least they reply promptly within minutes unlike Marriott Bonvoy that takes days/weeks if ever even for Ambassadors.
