Vegas is awesome but your money can run out fats if your not careful. I agree stay somewhere cheap, im just back from the Imperial Palace which we got for 50 bucks a night for 4 adults is fab. The trick is to just book direct throught the hotels websites. Have a look at a few hotels and decide where suits you. Then keep checking back on the sites for deals. Most hotels push there rates up on fri sat and sun. Even consider hotel hopping if that doesnt bother you, stay in a nice hotel and move to a cheaper hotel on the weekend.
