This has probably been covered a million times so sorry in advance but... OK, so me and my girlfriend just returned from Vegas, staying at the Mirage. We are now comfortably platinum Mlife. We play quite a lot, usually 100$ a spin each on roulette or 25$BJ , and also slots anything from 80c to 3$ a spin for long durations. After being asked a few times if i had a host i decided to speak with one and he comped my F&B and said next time make reservations through him. My question is what is the main benefits of having a host. I already earn pretty good comps and got a room for 7 nights free without host, so just wondering will there be a significant difference now that i have a host? Also i plan on staying half my next trip in a different MGM property, the Aria, are hosts limited to the casino they are based at or could i get a good deal from the Aria through the Mirage guy? Thanks.
