Royal Caribbean also wants people to actually go on the cruises they have booked. That means following up their down payments by paying in full before the final payment day. To make that happen, the cruise line's team that deals with travel agents has reached out to them with a major request.

A gastrointestinal illness outbreak on a Royal Caribbean cruise ship sickened 180 passengers and three crew members with unpleasant symptoms like diarrhea and abdominal cramps, according to health officials.

A drink package, for example, makes it so the cruise line does not have to deal with angry passengers who run up huge a la carte bills. Some people don't listen and, well, each adult beverage you consume makes it less likely that you will be concerned with the cost of the next one.
