Casino marketing rep comped my stay in August for 3 nights. She said "I can comp all 3 nights in a Delano Queen against your expected casino play to be done here during that visit". What does this mean? Is this a front end comp? I've always booked through my MLIFE account online. But offers are trash and they disappear unexpectedly. I earned 80k tier credits all from gaming the last two trips combined. October 2015 and May 2016. (2 nights each). Slots and BJ only.
