I just got an email offer from The Cosmopolitan for 2 nights free Sunday-Thursday valid January 9th - April 16th. I was in there one time two years ago to do the $100 promo. This works out perfect as we will be there the beginning of April. We have 3 nights booked at Aria using MyVegas rewards and now 2 nights at The Cosmopolitan!! What a great start to the trip!
