I so much prefer the Westin/Sheraton style bed to the nasty a** skanky wool blankets covered by flimsy sheets used at other, lesser, hotels. I cannot sleep at those properties as all I can do is imagine the (likely) disgusting person who used that blanket before me. If I wake up and realize that any part of me made contact with me, I run into the shower.
I am overstating things a bit, but the Westin/Sheraton set-up is so much more hygenic than those horrific blankets.
