There are pluses and minuses that can be tallied up on both sides. For "me" the pluses are more for Royal than Carnival. DW and I have cruised Carnival many times and we prefer the atmosphere on Royal. Drunks and poor behavior is not exclusive to just one cruiseline. Different cruiselines attract different types of people. This I believe is price driven. We don't mind paying a little more for the type of cruise we desire. There are people who are loyal to Royal and people who are loyal to Carnival and that's ok.
