We were able to do everything we wanted to do. We tricked and treated in all of the 'lands' and got on rides, listened to stories, and watched the parade (watch out for the headless horseman!), took pictures with characters, and just people-watched in general. It seemed that there was a lot to do so the crowds are well dispersed--the longest lines of anything I remember were the trick-or-treat lines in Frontierland (must have been giving away chocolate). Don't forget to wear a costume!
