Hilton just announced its first quarter 2013 promotion. You can get either double points or double miles for your stay at participating properties.
Actually, the promotion is not covering the whole first quarter in 2013 – it starts January 7th. And once you select double points or double miles you cannot change it after registration, so think first.
And you do need to register in advance.
Frequently asked questions can be found here.
As always there are several properties which do not participate in this promo, so be careful while booking these locations! The full list can be found here.
Regards,
Dieter
