CES is a major show, with thousands of people. Careful planning and consideration of your travel arrangements will pay huge dividends. Let's be fair, nearly 1 million folks will try to walk the same footsteps at the convention center, in the following 4 days. CES is annually the largest trade show in Las Vegas, and the town is fairly well populated with tourists. Since this is a big time in town, congestion becomes an issue, and things seem to move really fast, or not at all. If you don't know exactly what you are doing, or at least where you are going, you won't get there. Traffic jams, crowds, and lines will be the norm these 5 days. Either be smart or really patient. In the end you will need both. With only a few days to accomplish so much, you don't have time to wait. After a few years of trying everything, these are my reccomendations.
Everything is very Large in Las Vegas, so trying to walk will cost you a very large chunk of time. In addition, you will be walking a few miles in the convention center, and walking to see the sights for pleasure. You must conserve those legs for business and pleasure, so a bit of planning will behoove you. Time is of the essence for your days at CES.
