Howdy, Amy!
Thanks so much for your question! We're excited to help you plan your toddler-friendly Disney vacation!
I also have two small children, and deciding which parks are best for them and how many times we should visit is always a task! But no worries, I'm here to help!
I would definitely include
Disney's Hollywood Studios in the plans! If your 2 and 4-year-old are anything like mine, they are HUGE Disney Jr. fans. You can find Sophia the First, Doc McStuffins, and a few of the Little Einstein friends at Disney's Hollywood Studios. Also don't forget about the
Disney Junior Live on Stage, where your little ones will be able to sing-along with Mickey and a few special Disney Jr. friends. Toy Story characters and Toys Story Mania top the list of experiences that my toddlers look forward to at this theme park.
So, I would suggest visiting Disney's Animal Kingdom and Disney's Hollywood Studios in 1 day. You can start your day at either park, take a midday rest, and finish out your day at the other. Then you can spend the rest of the days at the Magic Kingdom.
If you don't have a park hopper pass, you could visit Disney's Animal Kingdom, Disney's Hollywood Studios, and the Magic Kingdom on separate days and the last day you could allow the little to choose which park they would like to visit again!
Amy, I hope this gives you a little help on planning out your days. If you still have questions, please visit with us again!
Wishing you magic and memories,
Korliss
