MGM Rewards is pretty great. Went last month to go to When We Were Young. I got 4 nights at Aria in a corner suite and my gf got my daughter 2 nights for her and her friend, all comped. I got $600 in free play and $350 resort credit, so one night dinner for me and the gf at Catch was free. She got $250 freeplay and $100 resort credit, which she used for drinks at the pool.
That stay rolled into enough points so that when we go back in May, both of us now have 4 nights comped, so we're taking a couple friends to see No Doubt at the Sphere. My resort credit will be enough to pay for one night of dinner for 4.
Also went to Herb & Rye off the strip for dinner one night. They have a happy hour that covers everything on their menu, including entrees. Got a nice New York oscar for $49.
