We just got an email offer from the GN which takes 25% off their rate from April to August of 2016. You can also get 15% off from Now until December and 20% off from now until May. There are some blackout dates and of course you have to factor in the dreaded resort fee. A coupon book is included at check-in. Since we already got a good deal on airfare, and we always stay at the GN although we don't play there, this was a decent offer for us to take advantage of. I booked a Rush Tower deluxe room and saved about $200 on our 6 night stay.
