Do this now: double points with Hilton HHonors
/Registration is now open for Hilton's winter "Double Up" promotion, whereby you can earn double points between November 1, 2014 and January 31, 2015, starting with your second stay.
I love staying with Hilton, but naturally make almost all my reservations using HHonors points. I have one "Points and Money" and one award reservation during the promotional period, so it doesn't look like I'll be earning any double points during this promotion.
Whether you plan to take advantage of the promotion or not, be sure to register now, before you forget, and find the list of non-participating properties here.
