What did the hotel say when you informed them about the problem? Did you confirm the problem with a visit to a medical professional? Scabies is almost always caused by skin to skin contact with an infected person, transfer from bedding to people is extremely rare and almost impossible, especially if the bedding has not been in contact with an infected person in over 12 hours.
If you feel my answer is rude, mean, snarky or in anyway not to your liking, I did my job. You don't need to tell me.
No private messages, I do not reply to them.
