My husband and I were at Beau Rivage in July and redeemed a 2 for 1 buffet. We are going again in October and have not been able to redeem the 2 for 1 buffet. An error code comes up and states my purchase limit has been reached. Called support and they told us there is a one us lifetime use on the My Vegas comps. Once you redeem you are not ever able to use that reward again.
