San Francisco is wonderful, but Las Vegas, Nevada is the Entertainment Capital of the World. Ironically, getting there, staying there and having a great time while you're there can be amazingly cheap. With Cheapflight’s help, you shouldn't have any trouble finding a round-trip flight for about $100 or less. Find a luxury hotel room for as low as $50 a night, at almost any time of the year. And what happens in Las Vegas stays in Las Vegas, so what are you waiting for?
If San Fran's sky-high prices are making a serious dent in your wallet, take solace knowing that you can probably have more fun while spending a lot less in Sin City. It's easy to get around and if you choose to explore the city on foot you can save money and get a little exercise while visiting one awesome spectacle after another, having a great time even if you don't drop a cent at the tables or in the slot machines. Unlike San Francisco, Las Vegas proper is flat, so no hills to hinder you as you walk, which along with all the fun should easily make up for the (dry) heat if you're exploring the Strip during the summer. Make the trip during winter to escape San Francisco's cold winter fogs - Las Vegas winter nights can get chilly but daytime is typically mild, sunny and pleasant.
