The Mickey pool in very busy along with the family pool. In seems deck 9 is where most of the people are along with deck 10. I never felt like it was too crowded on the sea days, in fact I liked the sea days better tean the port days.
Just depends. We went to the Disney trivia contest one sea day, only 3 other families showed up. So there are some sea day events that aren't crowded. Didn't win anything, boy they came up with some of the trivialist trivia I have ever encountered.
