What’s the Cheapest Time to Visit Vegas?

3. Holidays and Conventions

Travel to Vegas in November before Thanksgiving if you're looking for great deals. The services tend to be more expensive after the holiday. There are no big celebrations on the Fourth of July, so it is a perfect day to travel if you want to visit for a holiday.

All conventions and major events spike up rates; research upcoming events before booking your trip. Hotels and other services can be sold out during Super Bowl weekend events, the Consumer Electronics Show, and New Year's Eve. 

If you must visit during conventions, you can consider hotel rooms in Downtown Vegas and off-Strip casinos since they'll have less traffic.
