Thanks for the post: this is very interesting news. I have stayed at one of the Autograph Collection hotels (very nice property in Dearborn, MI) and have a reservation for the Glenn in Atlanta in the early Spring. The addition of this hotel adds an interesting LV option. I have just returned from Las Vegas, and I stayed a few days at the Renaissance, which I like, and which has the great steakhouse, Envy. But it is not on the Strip, and because I wanted a few days in that location, I booked at Aria for another few days. I saw the Cosmopolitan from the window of my suite in Aria, and was curious about it. This will be a great new property to try, and it has the bonus of enabling one to stay right on the strip and still earn MR points and nights.
