Hey Robin!
A huge, warm welcome to the Disney Parks Moms Panel! I am so happy to answer your question today and I hope that you will continue to send us your Walt Disney World Resort vacation planning questions.
Walt Disney World Resort calendars and park hours are normally finalized 180 days (approximately 6 months) in advance. Minor changes such as changes in Park hours, event cancellations and new shows/Attractions are sometimes made after the 6-month mark but these are usually on the website no later than 1-1.5 months from the date in question.
I don’t find that the calendars change drastically once they are finalized. You can rest assured that your
Advanced Dining Reservations are in place and will be honored for your July vacation. Please keep in mind that calendars may have last-minute changes for local or national emergencies. They may also have last-minute changes for severe weather.
Robin, I hope I have helped ease your mind and that have an unforgettable vacation at Walt Disney World Resort. Please visit us again if you have any more questions. We are always here and happy to help you!
With Lots of Disney Magic,
Priscila
