I'd try to negotiate directly with the hotel by promising them X # of nights in a certain period for certain upgrades whether its a RC floor, free breakfast or something. Once you hit either 3 weeks or if you really want, Hyatt hop your first week (5 nights, five Hyatt switches) you will have your Plat Status and since Hyatt posts really quick, you won't have to wait long to have your status (plat) but really I'd call the sales manager and ask for certain perks and before you know it you will have your diamond status anyway.
