Member Rewards Buffet Coupons?

Anyone have any luck using the MSS or Mirage coupons for 50% off as a single instead of buy 1 get 1? I was wondering how strict they were as I have a solo trip coming up. I was also curious to see if the Planet Hollywood $10 is back in play yet or if it is done for good?

I tried to use the Mirage coupon last year for 50% off and they basically laughed

You can ask somebody in the Mirage buffet line to share the coupon/savings with you.....
