Just received a notification yesterday that my reservation made with Starpoints for March 2019 will not be honored because the new hotel group (Accor) could not come to an agreement with the Marriott group. So anyone who had reservations made with Startpoints, Free SPG nights or SPG employee discounts will have their reservations cancelled.
Luckily, I got my points back from Mariott / SPG, but I had to spend an unplanned amount of money to book something else.
This will remind me to never stay at an Accor brand hotel ever in my life. What a bunch of amateurs.
