Very much a party scene out here - probably one of the better laid back pools I've been to, even with the DJ going
Plenty of seating but get here before noon if you want a good spot.
The lazy river has a lot of people just chillin' and cruzin' along in the desert sun but is great for cooling off in the Vegas heat. When the DJ gets going the wave pool seems to be the place to be since the DJ is located center stage and to the back.
Want a good seat while you eat - hang out at The Pub and watch the eye candy at the pool while you can have shaded seating ...not bad for an afternoon of just sitting poolside without being in the actual pool - see my review for the Pub here - http://www.yelp.com/biz/the-pub-at-monte-carlo-las-vegas
There is a bar at the pool for mixed drinks and beers or beer buckets of various sizes and there is waitress service walking around - BUT if its crowded the food service at the pool itself can take some time so keep that in mind
Otherwise hit this pool party up in the summer months and just enjoy yourself - remember what I said about the Pub at the Monte Carlo as well
