The trusty, reliable AAGU promo — that I’ve been using to give all of my friends, their relatives, and their relatives’ dogs instant Gold status with Hilton seems to have expired. I last used it towards the end of February.
The best current promo that I’ve found is SMGD. Call 1-800-548-8690 and signup for a new account or upgrade your current account with Origin Code SMGD. After four stays at Hilton properties, you’ll get Gold status which means point bonuses, room upgrades, and health club privileges.
