I was looking around at the dining FAQs on the DCL website and one of them mentioned something about character breakfasts, but I can't find any more info about them other than that they're only available on the 7 day cruises. We are doing the 7 day MR in two weeks and I would love to be able to do one for my kids, but I don't know anything about it. Do I schedule it in advance? On the ship? How do I find out when and where?
