From 2000 through 2009 I was solidly Marriott. Staying sometimes 120 nights a year, even achieving 75 nights on a year where I was "housed" in an apartment in Den Haag full time. They changed though in 2009 with significant devaluation of the points I hadn't had a chance to use (too busy earning). That, their price increases relative to other options (sometimes double), and not having a plethora of non-east coast Australia locations led me to switch over to Hyatt and Hilton. But... my wife's been using my points to stay in Soho with her sister (yes, it is her sister) and now she doesn't want to stay anyplace else. So here I am clawing my way back up to status (never lost silver due to the card). I tell you, it is tough without the lounge access. I even paid for it myself last week in SIN.
