Chicago to Las Vegas Travel Guide

One of the best things about flying to Sin City is that flights to this highly popular destination are really cheap, leaving you to spend your hard-earned cash on gambling and a wide variety of other entertainment options. Hotels offer some great deals as well, and you probably won't even need to rent a car, with most everything you want to see and do all close together. There are plenty of other transportation options, such as taxis, buses, your own two feet and free shuttles provided by area hotels. You may even get lucky at the slot machines or tables and pay for your trip.

Winter is a great time to escape Chicago for some fun in Lost Wages, especially if you don't like being cooped up indoors. This trip lets you escape the cold, blustery weather and enjoy the mild, dry Las Vegas weather while strolling along the Strip. But even during summer, Las Vegas is quite comfortable - it's a dry heat, and mornings and evenings are pleasant. Then of course there are all those spectacular world-class casinos in Las Vegas, where you don't have to drive miles only to find crowded tables and lousy odds on a riverboat.
