Last week all cruise agents selling RCCL, Celebrity and Carnival cruises were instructed by these cruise lines that they could no longer discount fares and anyone caught discounting their cruises would no longer have the right to sell their cruises. It is obvious to me that these cruise lines all have their own booking sites and want to recapture the 10 to 14 percent profit margins that they must pay to agents. I cruise at least 4 times a year and have personally seen the underhanded tactics that these cruise lines utilize to increase their bottom line. RCCL is probably the principle culprit in utilizing these types of tactics both with their passengers and agents.
