I never received any offers from mgm places in the past, other than "calender rates". After my last visit in Feb, when I played at Mirage, Aria(poker only) and Monte Carlo some. I started getting 1 free night emails, then I got 3 free from Monte Carlo w/ $100 in slot play, so I booked it for July 4th/UFC. Then, 2-3 weeks later, I got the same offer from Mirage, so I cancelled Monte and booked Mirage for same dates. I was estatic since Mirage has long been 1 of my fav casinos to visit. I just received another email from Monte Carlo, for 5 free nights + slot play(have till Aug to book). This is pretty crazy since I really am not too big of a roller.
