Okay, we need help. My sister and I booked on the Valor, and now her sister-in-law wants to go along and share a room with us. We took advantage of Carnival's sale a few weeks back, so we were upgraded (inside cabin) for the same price. I am wondering if anyone else has ever had to add a passenger to their room, and how much of a hassle it was?? There's no way I am adding another person to an inside room. My inlaws sell cruises and booked this one and said it would be a hassle to cancel our cruise, rebook, upgrade to a balcony or oceanview and more expensive (I know they really don't want to do it) We hate to tell her no, but if it's going to be a huge hassle, then we will have to I guess. Anyone ever done this??
