Hi Ahmed,
I hope you have a wonderful time at the Walt Disney World Resort!
There is no age restriction on
Kilimanjaro Safari or any other ride at the Walt Disney World Resorts. There are other restrictions such as height or health. All of the warnings and restrictions are listed at the entrance of the ride.
Given this, both of your children would be allowed to ride Kilimanjaro Safaris. I recommend early morning especially in the summer as the animals are more active. You should also head over to
Animal Kingdom's Rafiki's Planet Watch. Hop aboard the Wildlife Express Train and enjoy the
petting zoo and other up close animal encounters.
You also might want to head to Fort Wilderness and visit the
Tri-Circle-D Ranch and see the animals here. They even have Cinderella's ponies.
Wishing you a magical vacation!
Beth
