May in Las Vegas can pack hotels on and off the strip. There are a number of events, trade and industry shows, and conventions. Among the significant events that bring tens of thousands of people to town are:
- EDC – Electric Daisy Carnival

Deals on hotels can be found in January but you need to do your homework to find them. Las Vegas hotel rates are dynamic, meaning a rate can change daily and even hourly if demand increases or decreases. If you notice the rate for a room you already booked has dropped, call the hotel and ask for your rate to be matched. It’s not a guarantee, but like so much in Las Vegas, it doesn’t hurt to ask politely.
