Found this thread because I was curious why I got it. Checked in as an MLife Gold on 12/27, and was told I had been upgraded to Noir, which was surprising to say the least. After getting to the room, I found the notification from WoH. I am nowhere near the playing levels VG described, and I'm only around 50K base points.
Visconti--thanks for the tip. May try to do that at Caesars. Any chance they can see if I'm a 'fake' Noir? If not, hello Il Mulino.
