This just landed in my inbox. Hilton HHonors continues what has been a year of truly lucrative promos for members, most of which are (a) stackable and (b) have no properties opting out. Click on the image below to go to the registration portal (this one does not appear to be targeted. You just need to have the no-fee Citi HHonors Visa Signature). See the T&C after the picture. ¹ This offer starts upon enrollment and will end on 11/22/15. Earnings associated with this program will equal three (3) additional HHonors Bonus Points per USD $1 spent on stays at hotels and resorts within the Hilton Portfolio, net of any returns or credits. A "stay" is defined as the total number of consecutive nights spent at the same hotel, whether or not a guest checks out and checks back in again. Your stay must be completed and paid by 11/22/15 to earn the additional Bonus Points. The additional HHonors Bonus Points awarded with this offer are subject to a maximum of 5,000. Bonus Points earned on Base Points do not count toward elite tier qualification. Bonus Points will be awarded to the primary cardmember. Please allow 6-8 weeks from completion of your stay for Points to appear in your HHonors account. Offer applies to the account referenced in this offer, is not transferable or valid for groups, and cannot be combined with other select offers. To qualify for 9 HHonors Bonus Points per dollar spent, purchases including but not limited to charges at hotel restaurants, lounges, retail stores, or spas, must be charged to a cardmember's hotel room bill and settled using the Citi® Hilton HHonors™ Visa Signature® card upon checkout. Certain on-property vendors may not permit cardmember to charge to their hotel room, and such charges are not eligible to earn 9 HHonors Bonus Points per dollar spent. Hotels are responsible for classifying transactions to enable Citi to recognize which ones qualify for 9 HHonors Bonus Points. If Citi receives a transaction without that information, Citi is unable to recognize that it qualifies. Citi reserves the right to determine which transactions qualify for 9 HHonors Bonus Points. If you have transferred a balance to this account or do so in the future, you may not be able to avoid interest on eligible purchases, even if your promotional balance transfer has a 0% APR. You can avoid interest on eligible purchases if you pay your account balance in full by your due date each month.
