Does anyone know if Marriott discontinued the old SPG promotion where you got a second room booked for your family at 50% off?

I am trying to find this promo in Frankfurt and it seems that not one hotel is offering this when last year every SPG hotel had it available. I’m traveling the exact same week we did last year so it seems odd I can’t find that promo available.

Just curious if Marriott took away another perk that I have enjoyed many times in the past or if this just seems to be blacked out in all of Frankfurt on the dates I’m traveling.

Sorry if this has been asked before but I tried searching for it and didn’t have any luck.
