Hi Kelly!
Thanks for dropping by the Disney Parks Moms Panel with your question. I'm so excited about your upcoming Walt Disney World vacation. September will be here before you know it!
Don't forget to check out
Epcot International Food & Wine Festival (August 31-November 13) and
Mickey's Not-So-Scary Halloween Party (select dates in September-October...usually announced in the Spring) while you are there. These are two of Walt Disney World's most popular and exciting Special Events. I would highly recommend them both to you!
As far as your question goes, Park Hours are usually announced somewhere around 6 months ahead. I would suggest you keep an eye on the
online calendar, as Park Hours are added every day. And watch the
Disney Parks Blog for information about all Special Events happening in September. You are going to have a wonderful time!
Please let us know if we can do anything else to help. Here's wishing you the most magical Walt Disney World vacation ever!
