Thanks for your replies and help.
I’ve stayed diligent and finally got one to go through. A new one - of all things.
I got residence inn Lexington city center for 42,000 points.
Now, as a titanium, should I be expecting a thanks for booking but we’re sorry to tell you you don’t actually have a reservation message from Marriott ?? I ask, because as I’ve stated, I haven’t seen this occur on Bonvoy / website app before. Where they show properties available with a listed Bonvoy point total for booking and then don’t allow you to book it with points. Thanks for the input/help.
