love this hotel. have stayed 3 times. but i digress.
If you LOVE THE SMELL in Cosmopolitan (and who doesn't ---- it helps balance out the ubiquitous inevitable second hand smoke and booze stench in all vegas casinos):
GRAB SOME WOOLITE DARK, OPEN IT AND TAKE A HIT.
You will be magically transformed back into a world of hipster suites with terrace balconies overlooking the 'lagio fountains, long-ass lines for the subpar Marquee club, and a buffet of inefficient plating (*where the only "wicked" involved is the fact that the dishwashers have THAT many extra plates to wash)
Whenever I miss Cosmo I'm gonna wear my favorite "clubbin" shirt that was washed in woolite dark, take a deep breath in of the fabric, and pretend im in a better place .....
