Wow! You do have a family group here! Attack is the best word when trying to find what pleases everyone!
Make a plan for each day. Decide on
dining and make your reservations as soon as possible coordinating them with the locations you will be near. This allows for less running around the entire Disney property just to eat.
Bring the kids together and have them make their list of what they really want to see and do in each park. The older kids might want to go off and do some of the attractions that the younger ones are not able to because of height restrictions etc. Make your meals your meeting place if nothing else as it is a great time to hear everyone's tales of the day and to make sure all needs are being taken care of.
Take advantage of the rider switch for attractions. This information and other great helpful hints can be found on the
Little Ones page of the Disney website. Disney offers many services for families of young children and in my opinion it is the absolute best place to travel with infants and toddlers.
Trying to make everyone happy? No problem......you will be at Walt Disney World!
