We were there from Oct. 23-Nov. 3 this year and thought it was very doable and not too crowded. We are used to crowds (Star Wars Weekends, Marathon Weekends, New Years) and so anything less than that was great.
We never waited in a line longer than 20 minutes and took advantage of FP+. I would do that time of year again. We did avoid MK on Halloween and went to AK and it was great.
