Hilton’s 1,000 Reasons promotion is offering 1,000 bonus Hhonors points per night for every night you stay Thursdays, Fridays, Saturdays, Sundays and Mondays between November 1st and December 31st at participating hotels in the Hilton family. I guess it’s obvious, but you can get a maximum of 5,000 points per stay.
You need to register here.
You’ll also want to check this list of hotels that have chosen not to participate. It’s not a small list.
