From reading the threads, Mlife points seem to be less helpful than a human host could be, with regards to comps. If it is your first time in Vegas, but you are betting a lot (and likely losing a lot), do they seek you out? It seems to me they would want someone who can gamble a lot and would want to create loyalty to that hotel/casino. I don't mean to say we'd be expecting hookers and blow, but an occasional room offer and some free play, maybe a buffet or two? How much money would one have to gamble (ie the amount you bring with the express purpose of putting it in a slot) in order to be sought out by a host?
