The name says it all - this place is cosmopolitan.
I stayed at Wynn last year when I came into town for CES and thought it was fantastic (it still is) but The Cosmopolitan is where I hope to stay the next time I'm in town.
For those of you with children, I'd suggest you stick to the theme hotels; The Cosmopolitan is clearly for adults and they don't make any apologies for it. I was here without my kids but, as a parent, I can't help but see things from that perspective. No, I wouldn't stay here with them.
Check-in was a breeze. The staff was knowledgeable, helpful and they had a good sense of humor - like the laughing when I asked for an upgrade during their busiest week of the year. Hey, it was worth a shot!
The room was spacious and well appointed. It also afforded a terrific view. I don't know how many restaurants are in the complex but I think you can stay there a week and never repeat a meal in the same place. I did eat at a few and will review them separately.
