It is true that you are pretty safe when it comes to weather and some passengers suffer from sea sickness so the food lines are less after a storm. We have been through gales, and really bad weather but other than watching yourself when you walk there are no problems. We do have a problem with the Carnival ships as they seem to be more of the younger set and party cruises. One cruise we had with Royal Caribbean it was during a "College Spring Break" and it was great watching them have fun.. Carnival just has a bad reputation for parties good bad or difference it is a perception.
