Dear mhen,
We've missed you! We haven't noticed any activity on your HHonors account in more than nine months.
Remember, to keep your account active, you must earn HHonors points at least once every 12 months. Otherwise, all of your points may be forfeited.
There are lots of easy ways for you to save your HHonors points, if you act by 01 May 2012:
Stay at any of the 3,000-plus Hilton Worldwide hotels
Earn points with one of our many partners
Purchase HHonors points online
We hope you'll continue to enjoy all the privileges of HHonors membership. HHonors is the only program that lets you earn both hotel points and airline miles for the same stay and enjoy hotel rewards with No Blackout Dates. You can also redeem HHonors points for exciting travel and merchandise rewards, and enjoy extra care and attention every time you stay with the Hilton Worldwide when you're a member.
For more information on your HHonors account or to book your next stay, please sign in at HiltonHHonors.com.
We look forward to welcoming you again soon.
Sincerely ,
Jeff Diskin
