I've seen Mickey and Minnie in the Port Canaveral terminal in recent years, and maybe Goofy years ago? I am not sure about that one. The character line is the ropes in front of the ship model. We don't usually wait if there is a line, but if I see a cast member go stand at the front of the line, I'll ask who is coming out and get in line if it's not going to be too long. And I don't mind standing in the line if I'm going to be waiting around anyway if they haven't called my port time.
To the original question, we don't do matching outfits but I have kind of half on purpose put everyone in similar colors - like red/black/gray. I might do etsy shirts for our next cruise and then pick up DCL shirts on board for me and the kids to wear on the next cruise after that - dh has them already. For my kids the most important thing is to have their swimwear on or in the carryon so they can hit the waterslides as soon as possible.
