Hilton should really get on the ball and release details about the Q1 promo. SPG released their's and I'm making 50+ reservations for multiple nights each before the end of the week. SPG's promo rewards longer stays. Longer stays booked for more points at SPG = less nights in Q1 to spend at HH.
Get on it!
Also, what about a promo called "Nites and Bites" where after each 2-3 night stay, you get a free spiral-cut ham? That would sway me back to HH! @:-)
