To my mind there is no better sheet than the standard percale...200 thread count. The more they are washed, the better they feel. I have some on my own bed that are more than a decade old and are as smooth as silk. I have tried the high thread count cotton but they end up just feeling limp to me.
I do love old linen but I dont think those are even avaiable anymore.
I use a mixture of grey sheets...paisley, polka dot, plain. For the summer I spread a single white and gray sheet across the top. it fills the area below the pillows to the top of a folded cotton blanket...I did it to protect. From peoples bottoms, but it would guard against a dirty suitcase too.
Also I have a hotel luggage rack in the room....cheap from restaurantsupply.com.
