Get a cheap airfare during a slow time. Use Lasvegasadvisor.com to scope out hotel rates, a slow time is when the rates are low. You can also check via excalibur.com and look at a calendar, book through the hotel directly on the web. Watch the rates, they love to bump up the rates and give specials 2-7 days before, I got a 89 dollar rate at Treasure Island this way, it was up for a day.
