I really like the Aria - brand new and very high end - get ready for more of a high-rollers feel in the casino a lot of the machines and table games in here seem to have a higher minimum, you have to search a bit for the cheaper machines and table games
Over all a nice ambiance - definitely a younger more hip crowd, a bit of a smaller sports book. and a good sized casino overall that is pretty easy to navigate - quick tip stay next door at the Monte Carlo where it is a bit cheaper of a room to just crash in and go to the Aria for other experiences to save some money
