Stayed at MGM last month on comped offer. They told me when I booked the resort fee was going to be charged. Part of my offer was resort credit, which was enough to cover resort fees, but at checkout I asked to have the resort fees removed. They looked at my play and removed them. We used the resort credit for the spa charges. It's safe to say they are trying to start charging resort fees even on comped rooms, but you can still get out of it if you play...and you play nice with the staff. My friends were at the Monte Carlo and it was exactly the same. I am gold, but I'm sure bigger players probably don't have the fees at all.
