You may not come to Vegas specifically to gamble, but you're very likely to end up doing so once you get there. A study conducted in 2013 showed that although 15% of people visit primarily for gambling, about 71% do so during their visit anyway. Many people have been banned from Las Vegas for one reason or another. The city even has a "black book," with a list of people who are not allowed to set foot in any of the casinos.
