Great question!
We passed through the casino, from the Monorail, during out Thanksgiving trip and thought we really didn't care for the casino.
We revisted it during Xmas and walked around a bit more and decided we really liked it. The girl at the players club booth was really nice and I liked the modern, open feeling of the casino and sportsbook. They have girls come around with Ipads and place your drink order and then another waitress delivers the drinks, it was a quick/efficient system.
The photo's I've seen of the rooms are a little too hipster for me, but I'm willing to deal with it if everything is updated and new. I've grown tired of Paris, it just feels so old and worn out now.
