Hi Jessica! A lot to cover in a short space so will just give you some hints and directions to research more about your upcoming trip!
The Magic Kingdom park will be a must for your children! Every child dreams of seeing where Mickey is and the castle just adds to the magic. Plan at least one full day here and maybe more depending on what kinds of attractions and rides your children might be interested in. Be sure to see the parades, day and evening, as well as the spectacular fireworks show on select nights.
There are wonderful age appropriate attractions and rides at each of the other three parks, Animal Kingdom, EPCOT, and Hollywood Studios. It is hard to know what would best suit the interests of your children so the best way to decide how to plan your days and how much time for each park is to review their attractions on the disney website,
www.disneyworld.com . You can find them listed by scrolling over the Discover title at the top and then clicking on each theme park. Scroll down that page to find
Attractions. By clicking on this you can click and read about each one in that park and it will include special information such as height restrictions etc.
Develop a plan but don't think you have to do it all. Enjoy the time and reserve some dining which is always a good way to rest and relax during a fast paced day in the parks. You can also review these choices on the website. Reservations can be made 90 days out from your arrival by calling 407-939-3463.
Please don't hesitate to write back with your specific questions once you have started your plan.
