No real change in my stay patterns.

I've almost always been Marriott for business trips: I like their FS product better and they happen to be in ideal locations for my 3-4 most common destinations.

I continue to use the HH Amex just enough to stay Diamond and build a base of points deep enough to cover a 4 to 6 night stay at a resort property. This is where Marriott fails: no benefits for elites at resorts. So I go Hilton for those.

I also like HH's lower-end brands more than Marriott's. So I throw a few paid stays in the direction of HGI, HI, Homewood, etc. each year. Roadtrips to visit family, that kind of thing...

The devaluation hasn't changed my stay patterns mainly because my bigger spending was always Marriott to begin with. If my business stays were all Hilton, it might be a different story, as the devaluation would then bite a lot harder. It would depend on how inconvenient it was to switch to another brand.
