I hope you enjoy your trip. Like everyone said don't try to do it all, especially with a short stay. Make a list of must sees and try to track them out on the maps so that your not walking across the park all day from one thing to another. Our 1st trip I used some of the planning books that had itineraries for traveling with children. Expect the kids to be overwhelmed and tired, we still usually go back to the room and our son is 8, even if it's for an hour to watch tv. A must see with little girls is Storytime with Belle at MK they choose several children to participate in the show.
