I'll be the first to admit that I don't care for Marriott or its leadership, but it just seems odd to expect them to acknowledge an accident you had and send you flowers. I think it's very nice that Hyatt did that for you (maybe even a little strange), but to say Hyatt cares more than Marriott seems like a stretch. What about your favorite airline? Did they send you anything? Or your favorite credit card company? Your cell service provider?

And as far as where to post this, I would have put it in the Hyatt forum and said "look what Hyatt did for me" instead of the Marriott forum to say "look what Marriott didn't do for me".
