For a "cheaper" hotel the Monte Carlo is very nice.
I stay here because I get discounted room rates for my play, and I am very pleased with the rooms. Unless you are getting a suite, a hotel room in vegas is a hotel room. The rooms here are very standard.
The main amenity I like is the food court. In vegas, if you are not careful, you can quickly overspend on your budget. Having a food court with cheap food options for breakfast or lunch is very nice to keep the trip within budget.
The pools are also nice - but different. There is a lazy river and a wave pool. The river is very nice to relax and float around in.
The casino floor is decent - not huge, but has enough games.
The poker room is small, but I enjoy the friendly dealers. They are very nice and conversatons with them are enjoyable. Because of this, I enjoy playing poker at MC.
