Just returned from LV with stays at NYNY and MGM Grand. We did wander over to Park MGM and got a message that we were now receiving 4X points. This held true for 5 nights. We looked at others playing with cards in and did not see that message for anyone else. We did have tix for Lady Gaga ( awesome show by the way) not sure if that had anything to do with it, Anyone have any insights??
