If it was done, I doubt it was intentional. I've never had it happen to me. When I get into a stateroom, I check everything to make sure nothing has been overlooked. If there was something that should have been done that wasn't, I call the hotel staff and have them come and fix it. They send someone as soon as possible and sometimes it may take a few minutes because the stewards are getting the luggage to the rooms.
There are times, and the cruise lines tell you, that if boarding time is at 2pm and you get on at 11 to not go to your room until 2 because it may not have been made up yet from the previous cruise.
There is one thing I ALWAYS do whether it's on a ship or in a hotel and that is to check the bedspreads and blankets and if there is any dirt on either of them, I have them replaced with clean ones. ONE thing I can't stand is sitting on a bed that someone else has slept in and got their dirty shoes or worse on the spreads and blankets. I always take a can of Lysol too, and spray EVERYTHING my face will touch in the room...including the phone and remote control.
I can be pretty freaky about that stuff. Also, make sure you wash your hands after you go up and down the stairways after holding onto the bannisters. No sense leaving your cruise and going home with the start of catching a bad cold.
