A lot of strange things contributed to the crowds during Columbus Day week last year as well. The Electrical Parade had it's last run the Sunday night before Columbus Day. The hurricane wiped out park days for half of Thursday and all day Friday that weekend. As a result, it FELT more crowded because everyone was stuck at the resort on those days, and the food courts were overwhelmed. And, some people that talk about the crowds just don't follow good touring strategies. You should avoid MK on non-party days except for hopping over late. You should avoid Epcot on Friday and Saturday nights because of the Food & Wine Festival. You should avoid all parks on EMH hour days unless hopping over late. This is especially true of HS because it simply cannot handle large crowds at this time.
Great to read, thanks!!!
