This hotel is surprisingly simple. With all the gimics offered by neighboring hotels, the Monte Carlo isn't flashy, nor does it do anything to stand out on the strip. The best way to describe the reception area is elegant and simple. Beautiful marble floors, large floral decorations, and fantastic brilliant crystal chandeliers. I've basically described any hotel lobby in America.
The rooms are typical hotel room. Again, nothing special. They're nicely decorated and are comfortable. That's all I can really say.
The casino is nice. You can find your way around easily.
If you want a hotel without all the flash, not overly expensive (considering it's Vegas), but near the middle of it all, then Monte Carlo is a good choice. But don't expect to go WOW. You'll probably sleep there and then spend your day elsewhere.
