Welcome to the Boards. You and your family will love the cruise--one of the most relaxing vacations I've ever had. In your shoes, I would get a room at the Poly, and get a one day pass to MK. Although Sat. is not the optimal day of MK (it can be busy), if you've never been, it is the place to start. Then on Sunday, I would go to either Park Fare at the Grand Floridian, or Chef Mickeys at the contemporary for a character breakfast. Of course, this is just my opinion--I'm sure you'll hear many other options. Oh, and there are 3 waterparks--Blizzard Beach in the Animal kingdom area, River Country (near Wilderness Lodge) and Typhoon Lagoon. l
