Hilton is offering all members of Hilton Honors, both new and old, the chance to earn double miles or points.
For stays between now and September 30, 2011, they can choose to earn either double points or miles with the airline partner they prefer. They must register online before check in using their HHonors number or username.
Under the promotion, only the base points will be doubled not bonus tier points or other bonus points. Members can earn double points or miles for a maximum of two rooms during a stay, which ends at check out.
When members select whether they would prefer earning points or miles, their choice is binding at time of registration and cannot be changed.
Non-HHonors members can participate in the offer upon joining the programme.
The offer does not apply to stays booked as part of a package deal, corporate rates or for reward stays.
