It's never been one of my favorite casinos, but NyNy is actually a decent place to visit. First, they house Zumanity, so yeah, you HAVE to go there, and they're RIGHT next to the Monte Carlo, so that's a plus as well.
They had some of the neatest games on the floor too, like the Batman Game, with the old school Adam West bat man and Robin. I was greatly amused. again, this was a pass through and though I played in the casino, I really didn't get a chance to go through the hotel much at all.
