I've got a question for all of the MyVegas experts on here: I'm headed to Vegas in December with the girlfriend and my parents. To save my parents money on their room, I offered to book them under one of my comps at the Luxor, and then my girlfriend and I would stay at the Luxor on one of her comp offers. My parents have some MyVegas rewards that they want to redeem, but they are of the "must stay one night at an MGM property" variety. How would I go about making sure they'd be able to redeem these despite not having a room in either of their names? I figured at check-in I could add one of them to each reservation as an authorized user of the room. Thanks in advance for any insight.
