From January 1 through April 30 Hilton offered double points with no properties excluded. Hilton co-brand American Express cardholders got an additional bonus of 1000 HHonors points when paying for their first stay with the card during the promotion period.
For May 1 through August 31 they’re again offering double points, this time called “Unlimited Bonus” — Registration required.
This isn’t as generous as what Hyatt is offering right now but it’s a promotion and you’re better off earning double points than single points.
Hilton used to exclude many of its properties from promotions, they’ve overcome that which is a big win. And hotels are still generally full, with high average daily room rates, so there aren’t that many empty hotels to try to fill with promotions.
Instead hotel programs are offering promotions largely because other hotel programs are. They aren’t revolutionary, but they add value and activate members and help prevent other programs from poaching stays.
What double points means is an extra 10 points per dollar spent, worth about 4 cents (Hilton HHonors points are worth about $0.004 each), so an extra 4% rebate. I’ll take it!
