Hi Seth!
The best thing about Walt Disney World Resort is that no matter how many times you go, you can always find something new to try:)
My husband and I went on the
Keys to the Kingdom tour back in 2011. It was our first trip without kids since having them, so we wanted to try something different, that we couldn't do when our boys were with us.
We loved the tour. We learned so much new information about the Magic Kingdom and we got to see some really neat things that you would never get to see as a regular guest. I definitely think any Disney fan would enjoy it.
This is how the website describes it:
"This 5-hour walking tour explores the creation and remarkable growth of
one of the most beloved parks at Walt Disney World Resort. Explore
secret locations you’ve always wondered about and get the inside scoop
on some of your favorite attractions."
As for schedules, the Food and Wine Festival and Halloween parties should not interfere. You can call 407-WDW-TOUR to find out when it's available during your stay.
I hope this helps! Please let me know if you have any other questions.
