Hi Trisha,
Choosing between Disney's Hollywood Studios and Disney's Animal Kingdom is a tough choice, but rest assured, no matter which Theme Park you choose, you are guaranteed to have a magical time!
Disney's Animal Kingdom is home to many rare and beautiful species of animals, the Kilimanjaro Safaris Expedition is one of my family's favourite attractions at Walt Disney World. Be sure to check out a list of complete list of
attractions to see what else may interest your family. In my experience, my family is able to see and do everything in the park with time to spare. Our day at Animal Kingdom is usually combined with visiting another Theme Park in the afternoon, or some relaxation by the pool at our Disney Resort.
On the other hand it sounds like your family has an emotional pull toward Disney's Hollywood Studios, which offers Character Greetings with Lightening McQueen as well as several characters from Toy Story. Please check out all of the
Attractions at Hollywood Studios to see what would be a god fit for your family.
Have you considered the Park Hopper Option? You can choose to upgrade your Magic Your Way tickets at any time during your stay so that once you are finished at Disney's Animal Kingdom you can park hop on over to Disney's Hollywood Studios in the afternoon!
All in all, deciding what Theme Park to visit comes down to personal preference. In my opinion, I would spend the day Disney's Hollywood Studios. You do not want to leave Walt Disney World wishing you had met Woody and Buzz Lightyear or posed for a picture with Lightening McQueen. Either way, I'm sure your family will love every minute of their time spent at Walt Disney World Resort!
