I stayed a week at the Cosmopolitan during the recent adult tradeshows, so I asked the concierge to arrange for VIP passes to Marquee for us. It's a good thing I did, because the lines looked really long.
Being that I am terminally married, I'm not into clubbing that much, unless there is a live band or it's a sports bar, so I may not be the best person to ask, but I doubt that I have ever seen so much leg in my life, attached to such amazingly beautiful women (and I'm somewhat jaded, since I spend a fair amount of my time shooting hot models).
The club itself was incredible, with an amazing light show and sound system. Check out the
Marquee website, and not just the nightclub page on the Hotel website, if you want to see more of what the experience will be like.
I highly recommend the Cosmopolitan for anyone planning a stay in Las Vegas. The suites are spacious, and have several nice features such as a balcony (rare in Vegas - in my case our room overlooked the Bellagio fountains), Japanese soaking baths, a cool workout area (including tennis courts), a very nice modern art collection, and several outstanding restaurants...Blue Ribbon Sushi was excellent, as were Scarpetta (Italian), Comme Ca (French), and STK (great steaks).
The Wicked Spoon buffet was pretty awesome too...
