I know that halfway through my last cruise, my sheets and bedspread were changed on the Victory. I had spilled a bit of soda on my bed and cleaned it the best I could. Two days later I had new items without having to ask. And most hotels don't change the sheets everyday now. I stayed in four different hotels over my honeymoon a few months back and all had cards that said they would change the sheets every third day or if requested, more than that.
