Hi Joye,
Thanks so much for visiting the Disney Parks Moms Panel with your question. I like the idea of heading back to
Magic Kingdom after visiting other Disney theme parks. This will be a great way to end the day with your little ones, especially if they have previously been to Magic Kingdom and you know that there are particular attractions or experiences that they want to enjoy again.
Adding the Park Hopper Option to
Walt Disney World theme park tickets will give you the option of going from theme park to theme park every day. This includes Magic Kingdom, Epcot, Disney's Hollywood Studios, and Disney's Animal Kingdom Park. There is not a way to purchase park hopping for only one particular theme park; rather, the Park Hopper Option includes all four theme parks. My suggestion for you is that if you think you would like to return to Magic Kingdom at the end of your days at Walt Disney World, go for it! Purchase the Park Hopper Option so that you have that flexibility.
I hope that this information is helpful for you, Joye. Have a wonderful time planning your magical vacation, and please do let us know if you have any further questions.
