Hello, Faaiuaso!
Welcome to planDisney! I am so happy to hear you will be
celebrating the most magical season of the year at The Most Magical Place on Earth!
As you are aware, all Guests ages 3 and older are required to have both valid admission and a
theme park reservation for the same park on the same date. I am sorry to hear you are having a hard time making reservations. You will be visiting Mickey during the busiest time of the year at the Walt Disney World Resort so that is why you are probably not finding availability on certain dates.
I am glad you have already secured reservations for Magic Kingdom Park! I recommend that you keep checking
Theme Park Reservation Availability, as capacity may change without notice. I have just checked the calendar and it seems EPCOT is still available on December 21, and Disney’s Animal Kingdom Theme Park is currently available on December 24. Please note that availability is subject to change at any moment, so be sure to try securing reservations as soon as possible. Since you have tickets with Park Hopper option, you will be allowed to start visiting other parks beginning at 2:00 P.M., but again, the ability to enter another park is subject to capacity limitations.
I hope this information is helpful, Faaiuaso. I hope you can make more Disney Park Pass reservations and that you come back to visit us real soon with more questions!
Best magical wishes,
Thiana
