In my frequent visits to vegas i have found the best deal to be the Stratosphere. Just tell them that you want a good deal and when they give you a price, ask for a better deal. This hotel has 50% of its rooms empty at all times and as long as you pay more than the $2 it costs for the water you use and the maids cleaning your room they are profiting. Try saying something like "I want to spend most of my money on your slot machines, not my hotel room" saying this will almost definitely enhance your price saving
