Our trip days fall between 9/15-9/13 so I chose the closest to
my actual time.
We had these weeks already free for Vacation before
we even knew about FD.
I wouldn't worry about crowds, We've been to WDW
many different times of the year and it is always Crowded.
Just Enjoy yourself!!!
For us its POR 8-27 to 9-2. Wanted to start on sunday but I get off that day at 7 am and still have an 8 hr drive. So I'll drive during the night and nap when I get there.
