Hiya Abbigail!
Welcome to planDisney! I love that there are options when exploring Walt Disney World Resort! Four Main Theme Parks and 2 Water Parks plus all the other areas to explore make planning an itinerary a fun problem to have.
I suspect you purchased the
Standard Date-Based Theme Park ticket which can be purchased in any number of days ranging from 1 to 10 days. If that is the case then you can definitely visit
Magic Kingdom Park for two out of the four days you have purchased. If you add or have added the
Park Hopper Option then you can visit multiple Parks in one day. Otherwise, you will just visit one Park per day in any order you like.
Magic Kingdom Park is my favorite park and I always try to visit it at least twice during my trips. Nothing can duplicate the feeling of walking down Main Street, U.S.A. towards Cinderella Castle knowing that the day is going to be filled with magical moments. Make sure to look into purchasing a
Lightning Lane Multi Pass or Lightning Lane Single Pass so that you can enjoy your favorite or must-do attractions with a shorter queue. Magic Kingdom Park is truly the best Park to use for that as there are so many very good attractions that are eligible. This new system hasn't started yet but I bet by the time you come we will know a lot more strategies to make it worthwhile. If you have questions about this let us know!
Happy Planning!
