Sign up for Hyatt CC. They match to the 2nd tier of MLife (pearl? Silver? I have no idea). At that level I mainly play $10 craps and $10 BJ and some $.25 Video Poker and my wife does some small slot play. We usually get rolling comp offers at the casinos we play at most (NYNY and MGM Grand) every 6 months but lots of time we get 3 night offers from all MLife hotels. We try to go once (maybe twice...cheap from Portland) a year to ensure the comps keep rolling in.
