I have never been on a cruise before so please don't make me feel stupid. LOL my sister wants to surprise her kids with a Disney cruise next summer. But before she books he wanted me to ask you guys how much it really costs to go. I know the cost of the cruise according to the Disney website. However I am wondering if you have to pay to do the activities on the cruise. If she wants to let her kids do things on the boat, is she gonna have to pay extra for that or is it all inclusive aside from souvenirs?
