Houston to Las Vegas Travel Guide

Perhaps the most exciting weekend getaway in the nation, Las Vegas is one of those cities where everything is bigger and brighter. It's no secret that Vegas is a gambler's dream, and all the big hotels include casinos with a variety of slot machines and table games. The city also includes plenty of family friendly activities, including animal exhibits, zip line tours and gondola rides. It's easy to find direct flights from Houston to Las Vegas, Nevada, and it only takes about three hours.

When you're used to the humidity in Houston, it's certainly an adjustment coming out to Las Vegas. Since it's in the desert, it's a dry climate with hot summers and chilly winters. Staying on the famous Las Vegas Strip is the way to go, since it puts you in the middle of the action and you can reach most of the city's hot spots in a short cab ride. Las Vegas is home to excellent restaurants and beautiful night clubs, but if you end up gambling, remember that you can get free drinks from the casino's cocktail waitresses.
