No, I'm not going anywhere because of this. With me, Diamond is hard to make because of the lack of small city locations, so I have to generally rely on double-stay-credit and FFN mattress runs to get there.
I might end up cutting back on Hyatt, not because of this devaluation, but because of what my work travel patterns might end up being in the second half of 2010. I'm at 10 stay credits right now through a third of the year, and FFN usually means that I'll get 8 stay credits in 4Q if I need them. So the real question is whether I'll do 7-8 revenue stays between May 1 and the beginning of FFN, which would almost all be for work.
But given that I picked up 4 FFN nights at the Park Hyatt EZE this year, including two of the nights from four $55 HP mattress runs, I will stay loyal as long as it is logistically possible.
