I booked this hotel for my companies annual meeting. The sales department was very professional and easy to deal with. The casino has good location close to the City Center and almost in the middle of the strip. On most vacation search engines Monte Carlo is listed as a 4 star hotel. Prices were very reasonable for this resort and casino and shops are nice. The gambling areas are not crammed together so you dont get that hemmed in feeling. The rooms are very large, but are pretty no frills as far as I was concerned. A keurig coffee brewer, two bottles of water and a flat screen tv were the highlights as far as ameneties are concerned. One huge flaw of this hotel is the lack of WiFi and their ethernet internet access is not covered by the resort fee charge.
Overall this is a good value casino. As part of the MGM family you can stay here and take advantage of MGM's frequent free show ticket promotions. Monte Carlo and Luxor are the two cheapest 4 star hotels in the MGM group and probably on the strip. The guests staying at Monte Carlo were not the rowdy low brow bunch found at the Luxor, so if you are looking for a decent place to stay with good location and good prices, Monte Carlo is a good candidate.
