what is the best website for

booking a hotel in Atlantic City?.. I was thinking of booking something in about 2 weeks- is this too short of a notice to where it will be a difference in price?
Also, I wanted to stay at the Borgata, and I know its pretty expensive.. my friend told me that the last time she stayed there, she bargained with the front desk or w.e over the phone and got a better deal, I dunno how true this is? LOL

Thank you ladiessssss
