Aeroplan members who stay at Days Inn or Days Hotel properties in Canada or the U.S. can now earn double Aeroplan Miles or double TripRewards points for each stay until May 6. To earn the 500 Aeroplan Miles per stay (double the usual 250 miles awarded), guests must be both an Aeroplan member and a TripRewards member, and have selected the Aeroplan option in their TripRewards guest profile. They also need to register for the promotion online in advance, and complete at least one qualifying hotel stay during the promotional period.
