This is the line in the OP's post that jumped out at me because that would be a significant (and significantly guest-friendly) change to the Bonvoy T&Cs.
I see no alternative but to ask
iknowthings if this is indeed true and if there's any public document from Marriott that confirms this policy and can be waved at Bonvoy hotels. I strongly suspect that it's not true and this is merely a YMMV situation. But willing for my instinct to be wrong.
