Lets use MLife as an example and MGM and Monte Carlo. Why not try obtaining a host at that specific property rather than just one host for them all? Sure its the same company behind the scenes, but if the host at MGM knows you may stay at Monte Carlo would they maybe entice you with a slightly better comp at the end. Do the hosts have their performance reviews based on the people they bring in? Sure if your host is providing you with great comps it won't make sense but what if you feel your host is short changing you would it be worth a try?
