We noticed a huge amount of tour groups, esp South American groups. Epcot itself seemed ok, it was mostly the showcase that was rammed with people. AK, IOA, etc seemed as busy as most other Octobers I,ve been. Luckily not as bad as August but not as nice as April or november
Yes, I get what you're saying about the word "quiet" being a very subjective term. Especially given that everybody has their own opinions and perceptions of things. Will see if I can find where I read it was the quietest month. I'm 99% sure it was in a Disney affiliated brochure/book though.
