I love these fountains. I really feel like they're an icon of Las Vegas and one of the more classy ones at that. Its free to watch and no matter what angle you see them at, it will be enjoyable (although I recommend the front more than the sides). Its also really easy to reach as you're walking down the Strip so you don't have to go out of your way to see it. Also, shows are pretty frequent. I believe its every half hour? I'm not exactly sure but at certain "busy" times, the shows are more frequent. Stop by while you're out on the town! You won't regret it!
