Welcome to planDisney, Jennifer! I'm so glad to hear that you're planning a trip to Walt Disney World Resort this fall. I've also got a getaway to The Most Magical Place On Earth planned for this November, and since
Disney Park Pass has recently become a part of our world, I'm happy to walk you through checking out availability before you book your vacation.
Jennifer, if you want to check out the availability of Disney Park Pass reservations before you purchase your admission you are welcome to
have a look at this calendar. It will let you know which theme parks are still accepting reservations and which, if any, are sold out for the day. Since you'll be visiting the week of Thanksgiving, I recommend that you make your reservations as soon as possible since it's a very popular time to travel. At this time, it looks like you can still get reservations for
Magic Kingdom Park,
EPCOT, and
Disney's Animal Kingdom, but
Disney's Hollywood Studios has reached the limit for reservations beginning on November 22 through the rest of your trip so I recommend that you visit that Theme Park as early as you can during your vacation. It is possible that Disney Park Pass availability may change as guests modify and solidify their plans before their trips, so I recommend that you keep checking back if the exact reservations you want aren't available at the time of booking.
I hope this answers your question, Jennifer, and please let us know if there's anything else we can do to help you plan your magical vacation!
Jessica
