Got a mailing yesterday, (Snail Mail) that says: "For a limited time only, earn 2 extra Hilton HHonors Bonus Points, for a total of 5, for each dollar you spend when you use your Hilton HHonors card to pay for rental from Alamo, Enterprise or Natinal between 11/01/2014 and 4/30/2015. Terms and limitations apply.*" No codes seem to be required. But it might be worth mentioning to the Car Rental Counter if you are renting and using the HHonors AMEX. (Trying to decide whether this should go in HHonors, American Express, or Car Rental. AMEX wins) Mods, if you think this should go somewhere else. Move it, please.
