Hi Angela,
Good news! There's no height restriction for
Kilimanjaro Safari at Disney's Animal Kingdom, so every member of the family can enjoy the trip across the savanna to see the elephants, hippos, giraffes and more. In fact, your daughter is tall enough to participate in every attraction at Animal Kingdom if she wants, with the exception of Expedition Everest. The height restriction for that ride is 44 inches or 113 cm.
If you want to look at a list of all the
Walt Disney World attractions that are available to her, you can go to the link I've provided here and sort by height. Most of the rides throughout the four theme parks are accessible to those at least 40 inches (102cm) tall, so she will have plenty to choose from.
I hope that is helpful. Please let us know if we can answer any other planning questions for you. Enjoy your Walt Disney World vacation.
Wilma
