Anyone at the World this past Labor Day weekend? What were the crowds like? Is it typically slow?

We went this year 9/28 - 10/3 because of the Jewish holiday my kids had four days off so we took one on each end. It was much more crowded than I expected. I know this sounds crazy but in 2013 the Jewish holiday is the Thu/Fri of Labor Day so we're thiking a loonnnggg trip of Sat the weekend before Labor Day through the following Sunday. That way we get nine days/eight nights and my kids only miss two days of school!

Thoughts on crowds?
