Hello Leisha,
Thanks for stopping by planDisney with your question. It looks like you are hoping to visit Walt Disney World fairly soon. How exciting!
So, as you've probably heard or read, to visit one of the four parks you need a BOTH a theme park ticket and a theme park reservation. If you haven't already purchased your tickets, you'll want to check the
theme park availability calendar to make sure the park you want to go to is available.
You'll notice that the dates on the calendar have 3 colors: green means all parks are available, gray means no parks are available, and yellow indicates some parks are available. When you see a yellow date, click on it, and below the calendar it will show which parks are available. For example, when I look at April 1, it shows me that Magic Kingdom is not available, but you can still make reservations to EPCOT, Disney's Hollywood Studios, and Disney's Animal Kingdom.
Once you've figured if you can make a reservation, go ahead and
purchase your tickets and then book your reservation as soon as possible. Also, it's worth noting that if you add the
Park Hopper Option to your ticket, as long as you have entered the park where you made your reservation, at 2:00 PM (or whenever park hopping begins) you can head to a different park, no reservations required. If, for some reason, the park you want to go to is full, there will be a push notification on your
My Disney Experience app. However, this isn't usually an issue because other guests are park hopping as well.
Hope this helps. Have fun joining
The World's Most Magical Celebration!
Diane
