Welcome back Charlene! Thanks for your question.
I love spending Thanksgiving holiday at Walt Disney World Resort, but theme parks tend to be very busy. Many people will leave on Sunday night or Monday morning, so that from Tuesday on, parks tend be less crowded.
Depending on your family interest, I would save Tuesday for Disney’s Hollywood Studios and Wednesday for
Magic Kingdom Park. I usually prefer visiting Magic Kingdom Park in the middle of the week, from Tuesday to Thursday and prefer weekends for
Epcot. This is a fantastic park, and even when it is very busy, you don’t feel it is too crowded because of its big area.
Don’t hesitate to come back if you have further questions.
Have a magical day!
Gina V.
