Hotels and feathers

Why is it that the new "luxury trend" at hotels is down bedding and pillows? I stayed at the Marriott the other night while traveling, and had to call them to remove the down comforter and feather pillows from my bed. I don't think they changed the sheets, either, since I spent half the night not sleeping, but coughing, hacking, and sniffling.

It seems like an unwise practice since I know there are many people who have a feather allergy. Hotels? shape up! I don't think I'll be staying at a Marriott any time soon.
