It is necessary to exercise reasonable caution in every sense: outside the center are not the most prosperous areas, and the hub of gambling establishments attracts scammers of all stripes. Therefore, keep an eye on your wallet and do not leave the center at night.
If someone outside the casino tries to offer you a free ticket to a show or dinner, asking how long you're going to be in Vegas, don't take anything and reply that you'll be leaving in a couple hours.
