Yesterday (Tuesday) was very busy. Both parks. Lots of student tours with Disney Youth Education Series, as well as senior or other school trips. I would agree with what SDFAMILY heard about the weekend not being as busy. I went Sunday night at 8pm and things were GREAT! - Could walk onto several rides all through closing. Last night though, at 10pm things were still busy.
BUT up until 11am things have been great each day of course so.... Hope to see you there!
