A lot of us are looking around for holidays at the moment so just thought i'd give you a quick heads up .... Expedia currently have Up to 40% Discount on Las Vegas Hotels and Up to 30% discount on other Hotels !!
Worth a looksie .... hopefully this will be of use to someone.
There's also a code for up to 30% off (posted by creamhackered) which may work along with this (havent tried it)
