The end of the year is one of the best times to get great deals on rooms in Las Vegas. Apart from the peak times of Thanksgiving, Christmas and New Years the rest of November and December are slow so its a great time to save money on your trip. Most of the hotels have packages where they throw in things like free buffets, drinks or show tickets to make you visit. Las Vegas at the end of the year can get chilly especially at night and not all the pools are open but its still warmer than most of the country. Check out the hotel websites for deals and packages and you can save even more if you can be flexible with your days.
