I love the Cosmopolitan!  Every facet of the place exudes cool, class, elegance, and sexiness.  The guest rooms are among the nicest, most modern, and well appointed to be found in Vegas.  The restaurants are first-rate.  The Vesper, the Chandelier, and Bond are exemplary bars manned by friendly, extremely skilled bartenders crafting some truly inspired cocktails which are the best on the Strip.  There are plenty of blackjack and craps tables.  The dealers are personable and professional.  The cocktail waitresses taking care of gamblers are attractive and attentive.  The resort staff, from the reps at the registration desk to housekeeping, is professional and proficient.  The Cosmopolitan would be my first choice to stay and play every time I'm in Vegas.\n\nSo, you may ask, why the 1-star review?  Carol W and I went to Vegas for Thanksgiving staying from Mon to Sat.  Our respective families joined us there and were also staying at the Cosmo.  Midweek stays tend to be less busy in Vegas and the week of Thanksgiving is an extremely low period for Vegas tourism.  As such, I called to speak to a casino host to see if I could get a better room rate than was being offered online on the Cosmo website or through Expedia/Travelocity/Orbitz/etc.  We do the overwhelming majority of our gambling as well as eating and drinking at the place we stay in Vegas.  The host I spoke with (who shall remain nameless) offered to COMP our stay...NOT simply offer us the casino rate for the room, which was $150/night Mon-Thurs and $245 for Fri night for our Terrace Studio room.  I fully understood that this comped room would require me to gamble at a certain level of play throughout our stay (although the host did not state what this amount would be).  While I had multiple offers from other Vegas properties for comped or deeply discounted rates (much deeper than the Cosmo's rate), we decided to stay at the Cosmopolitan.  However upon our arrival, we discovered our room was being charged at the casino rate NOT comped.  I attempted to contact the host that I'd spoken to on multiple occasions without success to get the discrepancy resolved.  At the end of our stay when it came time for us to checkout, I was told that the host would review my play and comp me accordingly, crediting it back to my credit card, if I'd earned it.  This was NOT the agreed upon arrangement that I thought we'd made prior to deciding to stay at the Cosmo.  Next time (not that the Cosmo will see a next time from me), I'll get it in writing.  The total amount for our stay ($966), while not inexpensive, certainly was manageable. \n\nI'm not a high roller; I never claimed to be one!  I never asked to be comped for our entire stay.  If you couldn't comp my entire stay since I hadn't established a history of play at your property, then you should've said so before I committed to staying at your property.  If you could only offer me the casino rate, then you should've said so before I committed to staying at your property.  I would've stayed somewhere else and saved myself the money I spent for a room that I spent very little time in!  However, most important to me, it's simply a matter of principle.  If you make me an offer to comp my stay, you should live up to it.  We both know that you would've made your money back from me and then some!  Your actions showed me how much you value my business.  \n\nI'm not holding my breath expecting to get any part of my stay credited back to me.  Cosmopolitan, even though I do love you, I do know how to quit you.  You'll never see me in one of your guest rooms or at one of your tables or machines again.  It's a matter of principle.
