For anyone considering 3-nights (Thurs-Sun or Fri-Mon), you can snag the Marriott Suites LV for ~$95/night using a Buy 2, Get 1 free promo from Hertz. Use the code "HPR" and search for a 3-night stay (incl. a Sat night) and you'll come up with it. It includes the third night on the costs, but they say the third night will be deducted from the bill at check-out (probably so people don't stay 1 or 2 nights at the discounted price and bolt).
The Marriott Suites is located over by the convention center and a little south of the LV Hilton. Right by a monorail stop and only a few blocks walk from the strip. Haven't stayed there myself, but having stayed west of the strip my last time there, it's probably considerably better, especially since the "real" strip hotels I'd like to stay at are well into the $200s per night.
I'm throwing that into my big cauldron of things to consider. I'll be trying to come out Fri afternoon/eve if there are empty seats...which there should be. I hope.
