We were loyal MGM players from 1997-2010. We travel to Vegas monthly for a 3 night stay. Over the past 4 years we have been giving MLife (Aria/Bellagio/NYNY) less and less play as we transitioned to CET. We kept booking Mlife offers to take advantage of free play and other perks. Each time we did, we usually zero played or low played the MGM casino in favor of playing at a CET brand hotel. Each time we thought Mlife would figure things out, we would get another offer. After a while we stopped using our hosts and just booked the offer. We are now going to move back to MGM/Mlife for many reasons. Our play was about $2,000 ADT for 1997-2010, then maybe $100 ADT for 2010-present, and will now return to $2,000 ADT or more from this point forward. How long will it take for the "computers" to forget our past 4 years?
