In today's economic climate, things will change. It was inevitable that cruise lines will try to make up for lost time by booking as many people as possible.
However, if you cruised anything in the past and observed the insane crowds it just became uncomfortable to do even the most menial things on this ship. Even trivia games were full capacity.
Sure, over time it was ok to find some times where things weren't crowded but I'm not booking a vacation to always plan on crowds.
