When we were in Vegas in September I stopped into the Cosmo and took advantage of their lose 100 get 100. A few weeks ago I received email offer with 2 free nights and 100 comp. I thought it was a very nice offer since I am diamond with CET and confine my play to their property. The offer says valid through Feb. 28 2013. Since we are going to Vegas Feb. 27 and 28th I called to make reservations the gal said offer is not good on the 28th. I did not argue with her just made the reservation for 1 night and she said she would immediately email confirmation. I have not received confirmation (reservation made about 5 days ago) but in re-reading offer it clearly says good through the 28th. Doesnt that mean it should be good for staying the night of the 28th?
