Las Vegas only gets about 4 inches of rain per year, but when it rains here, it pours — sometimes flooding streets within minutes. If that happens on your vacation day, you need options ready. The good news: Las Vegas has more quality indoor family activities than almost any other city in the country. Here is what to do.
