Oceania (I think) rents on deck "cabanas" by the cruise or by the day
NCL is ticketing some of their shows on Epic - are they charging for Blue Man Group
"Gratuities" on some lines are no longer optional - though for other lines they are no longer billed - that covers your service fee for room cleaning and the MDR.
Cunard still has class dining based on the cabin you book.
