I didn’t even realize this promotion existed until I logged into my Honors account during a recent stay. I had recently used my American Express Platinum card to enroll in complimentary Hilton Honors Gold Status and saw the offer on my account overview page:
Earn 7,500 Hilton Honors Bonus Points – Register to earn 7,500 Hilton Honors Bonus Points after you stay 2+ consecutive nights by August 7, 2017 and pay with your American Express Platinum Card.
Now, the T&Cs you’ll see below specifically state that you have to use your AmEx Platinum and that the “offer may not be combined with other select promotions, offers or discounts”. However, like with most Hilton promos, the points for multiple registered promos posted. Even better, I received the points without using my AmEx card…including an AmEx online booking bonus!
