Normal
I have never had a problem with carrying luggage on or off of any cruise line (Carnival, Princess, HAL, Celebrity, NCL, RCCL and Cunard). Usually I take one carry-on case with wheels and a duffle bag. If you were to attempt to carry-on a large suitcase, however, it may not be able to fit through the X-ray equipment at check-in, but you would not have any problem at debarkation.
