Hi Lilli Jo and welcome to planDisney!
How exciting that you'll be ringing in the new year at Walt Disney World! I have no doubt that you will have the best time partying the night away next weekend.
After looking at the
Park Availability Calendar for 12/30 and 12/31, I have some not so magical news to share. Currently,
Magic Kingdom Park is unavailable for 12/30 as well as
EPCOT for 12/31. The holiday season is the busiest time of year at Walt Disney World with Guests traveling from all over the world to experience the festivities of Christmas and the new year, so tickets and park reservations sell out quickly. Guests do change their plans, so it's possible availability will open up in the days leading up to your visit, so I suggest you keep refreshing the calendar to see if more tickets become available. You can
purchase park tickets for another theme park that is available and try to park hop after 2:00 PM, but that is only if the park you want to hop to is not at capacity and is allowing park hopping for the day and you won't know that until the day of. Something to note for doing this is that you have to visit the park you have a reservation for first before you hop to a second park after 2:00 PM.
I'm sorry I don't have a better answer for you and am crossing my fingers that you can find availability so the rest of your party can join and celebrate with you. Please
stop back by and visit if you have any additional vacation planning questions.
Have a magical day!
Leslie
