Getting good hotel deals

Hi
I am going to Vegas in November and as yet have not arranged any accomodation.
Would anyone recomend waiting until the day of check-in to book a room. My thinking is that I could get a good rate from a hotel trying to get rid of it's last few rooms, can it work like that?
I am not bothered about moving hotels during my stay, I would like to stay a few of the nicer hotels and get as good a rate as possible.
I appreciate your thoughts.
