Accor loyalty members can earn quintuple points when staying at one of the brand's participating hotels this year.
The promotion is to celebrate the fifth anniversary of its Le Club Accorhotels loyalty programme.
Members of either Le Club Accorhotels or Accor Advantage Plus must register for the offer online by February 18 and then stay at a hotel by December 31.
The offer is only valid for one stay and a reservation for multiple rooms only counts as a single stay.
A statement reads: "The reservation for the stay must be booked online (via accorhotels.com or the site of one of the brands participating in the Le Club Accorhotels program), using our accorhotels.com mobile application, or through the Accor Reservation center. Other booking channels are not eligible for this offer."
The loyalty card or member number must be provided at the time of reservation, and must also be presented at the hotel reception desk at the time of check-in.
Earlier this month, Accor announced that it will add a second Berlin hotel to its luxury Sofitel brand this Saturday (see news, January 1).
