I'm going to Vegas for a post holiday trip on Dec 26 and staying at Sunset Station. I was planning to pick up a discounted ACG guide since I thought the coupons were good until Dec. 31. Then I checked the coupon preview through American Casino Guide's website and saw the coupons for Sunset Station expire on December 23, 2014. (A lot of other coupons go til Dec 31, but not Stations.) So if I get a 2015 version instead, can those coupons be used in December of 2014? Or are they only valid starting January 1? I'm hoping there's not a "dead zone" for coupons right when I'm there!
