Question about hotels

I have never had an issue come up but I have heard of others that have. Has anyone ever had any negative dealings with a hotel when it came to your incontinence? I can remember reading somewhere that there was a person that came into his room after house keeping cleaned to find that the staff put a vinyl bed sheet on his bed without saying anything to him. I also remember seeing that there are some hotels that require to be informed if you have incontinence or a bed wetting problem. Is there any truth to either of these stories? \nThanks
