There are of course rest room in every casino you will visit, however one thing that may be worth doing when you are visiting a large casino you have never visited before is to take a good look around that venue and make a note where everything it! One thing that you will notice about any casino you do visit is that there will no clocks in that venue and there will be no windows either! As such it can be very easy to lose track of time when you are in a land based casino, so perhaps it would be advisable to wear a watch!
