You may win, but chances are you won't, but the cost of the entertainment of playing is worth it. To play a slot machine you don't need any skill, just a few bucks to have some fun. If you are intimidated by gambling but want to try it, all the casinos have a courtesy desk that can give you the basics. You don't have to gamble to have a good time. The HardRock has a ton of memorabilia you can spend hours looking at and reading about. You can walk into any casino and enjoy a world-class meal, ice cream, subs, shopping, and more.
Plenty of characters, multiple places to eat, carnival games, rides, helicopter rides, go-carts, and yes casinos. One of the greatest places in the world to people watch, in my opinion.
