Went in November 2016 for the cities and countryside exhibit. It was 47 pieces in two gallery rooms. You get the audio guide with admission and at first I was disappointed with how small it is, but the more I studied the art the more I realized how well the collection is curated and how well the audio guide makes them all interesting. Every piece was special in some way, always tied to the theme of the collection but very different from other works even if they were by the same artist. It's all very accessible to the art novice like me and I got a lot more out of it than I was expecting. I spent 2.5 hours there and it went by quickly. I trust the Bellagio to put on a good show and will definitely make this a standard part of my Vegas visits!
