It's funny, I frequently read about people getting lost / turned around in side casinos. My Mother is one of these people. She gets lost so easily in casinos. Me on the other hand, I never get lost. The layout, signage, etc is rather easy for me to remember and to navigate. That being said, if i had to choose the most difficult casino to find my way around in I would have to go with MGM. There have been a couple occasions where I really had to concentrate to figure out where I was. The easiest to navigate has to be South Point (big rectangle) or one of the tiny ones downtown.
