Location, Location, Location! It's right next to city center and close to Planet Hollywood, MGM, etc.
I was very surprised by Monte Carlo. I was expecting a budget style hotel (for Vegas anyways) and we got anything but that. The rooms were better than I had expected and have flat screen TVs and a nice ipod hook up for music. The pool was great, we loved the lazy river and the big hot tub. If you're going to be sleeping late keep in mind that the walls are fairly thin and there's also a huge pool party blasting music we could hear from the 22nd floor. I like the casino here too, it's not too crowded and I had fun at the craps table, great dealers for the most part. I would stay at this hotel again in a second!
