Bally's and Paris. They're connected underground, back near the monorail entrance. It seems casino/hotel builders have learned a lot in the last 5 or so years, since the newer place (like Paris) are an almost immersive experience, in an odd Disneyesque unreal way. There's no sense that you're actually anywhere else but inside somebody's recreation of Paris, for example, it is just a manufactured Star Trek alien zoo recreation sort of feel.
