Amex just recently started offering Hilton HHonors™ Gold Status for all of its AmEx Platinum members. Which by this time you should have both the Regular Version and the Mercedes-Benz version, both have their combined $925 annual fees waived for a $400 airline credit to use annually. Plus $100 each for global entry for you and a friend.
HHonors membership was easy I called the number on the back of the card and they gave me a new HHonors number right away. You can also link an account if you already have a number. This also can be registered online if you don’t like calling anyone.
