Hi there, I'm staying at the Signature at MGM Grand for our trip in May. I'd like to use my LP to get the $50 Freeplay at MGM Grand and also the free buffet reward - both of which say they are restricted to MGM Grand guests. What I want to know is if anyone has been able to use here rewards while staying at The Signature? Or do you have to be a guest in the main MGM Grand hotel to use them? Thanks in advance!
