I noticed some people writing reviews for either the pool or the concert venue that it turns into at night. I would like to make this review about both.
First i'll start off by reviewing the pool itself, during my last trip there everything was pretty great. Tons of cool people mostly my age mid 20's but you also saw some kids and older people every now and then. The vibe was really chill and people were tossing beach balls around all day. Other pros about the pool is the amount of lounge chairs that are accessible to everyone. Most upscale pool areas have reserved seating everywhere but I guess that's where Marquee Dayclub comes into effect. Only downside to my time there was that the sun dies down rather early because of the location.
Recap:
-Chill vibe with a DJ spinning tunes.
-Lots of free lounge areas
-Good looking people
-Sunlight fades early
-Pool not that big compared to other pools but the Cosmo has 3.
Now to my review of the concert venue portion. We were fortunate enough to be staying at the Cosmo when Foster The People were performing there. Now I must state that I didn't actually attend but my Wraparound suite was positioned 54 floors up overlooking the whole thing. From my balcony I was able to clearly see and hear everything from the hundreds of glow sticks people held up to my friends being able to sing along to every song. The place is beyond amazing on a summers night in Vegas. If you get the chance to see an artist you like there definitely do so!
Combined score of 4 stars
