My husband and I are in the beginning stages of planning our first trip to Disney World with our four children. It will be the first trip for any of us. We are hoping to go in mid-to-late April 2015 to take advantage of spring break for the kids. Planning to stay a week. Kids are 14 y/o girl, 10 y/o boy, 8 y/o girl (who will turn 9 the day after we return) & 4 y/o boy. Would love to hear your suggestions of must-dos, as we feel a little overwhelmed! TIA for any help you can give us!
