In all, I had a good stay at the Monte Carlo. Compared to other hotels on the Las Vegas Strip, the Monte Carlo has central access to elevators and attractions. The rooms were well kept and clean. They didn't have free Wi-Fi access but you could plug into an Ethernet cable if you need to access the Internet in your room. The price for the room was reasonable as well. However, a hotel room is really only for sleeping in Las Vegas.
They have a casino, of course, along with various restaurants, a small shopping corridor and the Blue Man Group. If you have a chance to see the Blue Man Group, do it, because it's a fun and interactive show. The Monte Carlo should be lucky that they are able to have this show at their casino.
I'd certainly consider staying here again while in Las Vegas.
