If that's the case then I'd say: jump ship!
Jump to where? I'm top level at Hilton, Hyatt and Marriott and the experience is the same at all of them. The Hotels don't care about loyalty right now - their occupancy rates are very high and they are trying to squeeze every penny from every traveler. The fact that I stayed 100 nights a year at Hilton from 2008-2010 when their hotels were empty doesn't matter much.
