Hello, Courtney!
Bringing your boys at ages 2 and 4 will be such a treat for everyone!
Going to Magic Kingdom is absolutely a must for your trip; good call there! While you would certainly have a fantastic time at any of the other three parks, I suggest you go to
Disney's Animal Kingdom on your other park day. Here, there are so many wonderful attractions, hands-on activities and family-friendly entertainment; your boys will surely have a blast.
First, head over to
Kilimanjaro Safaris early in the morning, while the temperature is cooler and the animals aren't looking for shade. Your whole family will be amazed by the experience! Be sure to take note of the times for both
Festival of the Lion King and
Finding Nemo - The Musical and work your other activities around viewing both of those wonderful shows. Don't miss It's Tough to be a Bug, TriceraTop Spin, and take the Wildlife Express Train up to Rafiki's Planet Watch. There, you'll find lots areas dedicated to the preservation and conservation of animals, including a petting zoo,
Affection Section.
At some point in your day, be sure to go to
The Boneyard to let the boys climb, slide and dig out that energy they'll have stored up throughout the day. At that age, my little guy could have spent hours in that one area alone!
Have a wonderful trip! Be sure to send more questions as you think of them; we love to help!
