Hotel rates in Las Vegas can vary wildly depending on time of the year, demand or convention traffic. One of the ways to save money on a room is by being flexable on your dates if you can. Generally Sunday through Thursdays are the cheapest days so if you can visit on those days you will save money. Fridays and Saturdays and Holidays are the most expensive times in Las Vegas. Other times that are expensive include Super Bowl weekend and during big convention shows such as CES or COMDEX. When you are checking room rates online adjust the days and see if you can save money. Also if you are staying somewhere like downtown check the other hotels because you could find one cheapest one day another one the next and if you don’t mind switching hotels they are real close to do that.
