I believe that was everything on Disney. If you want to look, Go to Disneyworld.com, scroll to the bottom and click park hours. That gives you a view you can look for up to 10 days.
If you don't like that layout, click on one of the park names, then on the left hand side click calendar, and then go to October 2009.
Takes some fanangling, but you can do it. I hate navagating through Disney's site. some of the park hours on Disney.com are different than the DIS too, so keep your eyes open.
