Hi Stephanie,
I'm so sorry to see that
Magic Kingdom doesn't have open reservations for the dates of your trip. While I wish I could wave my magic wand and say, "bibbidi bobbidi boo" to open up some spots, my Fairy Godmother powers are not that strong. However, all hope is not lost.
Sometimes, people do cancel their park reservations and park availability opens up as the date gets closer. You could just wait and
keep a very close eye on the calendar, because if spots do open up, they will be taken quickly.
Another safer option, and probably what I would do, is to add the
Park Hopper Option to your tickets. Yes, it's an upgrade, and it still won't guarantee that you'll get into Magic Kingdom, but it will greatly increase your chances. Basically, you'll
make a reservation to a different park, whichever other park you want to visit, let's say EPCOT. You'll start your morning in EPCOT, then at 2:00 PM (or whenever park hopping starts for the day) you can head to Magic Kingdom without a reservation as long as you visited the park where you do have a reservation first.
This is subject to park capacity, and it is possible that the park may be filled up to the point where it's not allowing park hopping, but most of the time you'll be able to hop without an issue. If park hopping is unavailable for a certain park, you'll receive a push notification on your
My Disney Experience app, and there is also a phone number you can call (407) 560-5000 to double check.
So depending on how many days you are visiting Walt Disney World. You may want to plan making reservations for a park where you plan on spending the morning and hop over to Magic Kingdom on two separate days to be able to get a full day of Magic Kingdom fun!
Hope this helps. Have a magical vacation!
