Welcome back John! Thanks for stopping by with your questions.
September is a good period to visit
WDW. The weather is great and Disney Theme Parks tend to be less busy. Because of the amazing
Epcot International Food & Wine Festival, Epcot will be busier than usual, especially during weekends, when you can find many groups enjoying the event. Waiting time in lines for attractions tend to be a little longer than normal.
If it is possible, I recommend you visit this enchanting park on weekdays during this Festival. I have been to WDW twice during this event and I remember once we decided to visit
Epcot on a Saturday and it was very crowded. It was not a good experience to my 6-year-old daughter; we found long lines for all attractions and too many people walking around the World Showcase lagoon.
Hope this helps your planning. Come back to visit us again soon if you have further questions.
Have a magical day!
Gina V.
