One of the best ways to get a great deal on a trip is to go on a slow week. Check the Vegas Covention Center schedule. If there is a convention in town… Guess what… Normal or elevated pricing. If it is a slow week, e.g. no major conventions, you will get a good deal. Some of the best deals on Vegas is mid summer. Usually it is too hot that most convention planners shy away from those dates. Worst times to go? Holidays… Believe it or not Christmas is one of the busiest times of the year.
