I have been a platinum member at Mlife for years and always receive at least 3 comped nights with about $150 of free play, $100 in resort credit and possibly a couple of show tix. I've had comped nights at NYNY and Mirage. Another interesting bonus of being an Mlife member is you can play the Facebook game MyVegas. It's a completely free game where you collect loyalty point. You can cash in those loyalty points and get free nights at all the MGM resorts. Combined that amounts to 6 comped nights at any given moment in the year.
