This lovely and relatively new hotel & resort in Las Vegas is first rate! Vinny and I stayed there this summer during a quick jaunt to Vegas and really enjoyed the hotel and all of its amenities. When we first checked in, we didn't expect we'd have a good experience because right off the bat we had to wait in a 45-minute line to check in, and then, the hotel screwed up and didn't have our reservation correct. Fortunately, the folks at the Cosmopolitan more than made up for it by giving us an updated room free of charge-- and, I must say, the room was amazing!! It was a large 1 bedroom suite w/ a balcony overlooking the Bellagio hotel and fountain (yes, the very one where they do the daily fountain and light show-- what a view, I tell ya)! Plus the room had a large sunken tub and walk-in shower, a large living room seating area, and high-tech work space (yep, sadly, I had to do a little work on the trip even though we were mostly there for vacation, but the work space turned out to be a godsend for me).
Other great features of the Cosmopolitan include their casino (it's modern looking and packed with lots of high rollers and beautiful people), their abundance of restaurants and shops, and their large pool recreation area, which features a couple of outdoor bars and plenty of lounge chairs for relaxing.
Note that one of my favorite things about the Cosmopolitan, believe it or not, is their Pizza restaurant. Check out my review of the Pizzeria @ The Cosmopolitan. Some of the best pizza I've ever had!!
