Had awful experiences in: Washington State (all over), Silicon Valley, Tampa Bay, Dallas, and Salt Lake City. Mostly Marriott-owned places FWIW, but I checked and all the surrounding hotels had the same issues. The staff at the hotels were nice and they were doing their best, but they were hilariously understaffed.

I stayed in a few non-Marriott hotels in northern Japan and didn't have any trouble there beyond the normal Japanese hotel badness (they're clean, but insanely cramped, expensive, and uncomfortable)
