Hey folks,
I have just checked into the awesome Cosmopolitan. As a Platinum, I was offered the following:
1) $10 credit or 1000 points
2) Upgrade from a City room to a Terrace Studio
3) 15% discount at Wicked Spoon plus the use of the express line for free
4) 2 PM check out
5) Free use of the Autograph lounge
Hope this helps those of you who are Platinum.
Happy Holidays!
