We have been twice, and I agree that you should arrive at 4 - I would recommend the first parade - we stayed at the entrance and could see everything very well, including the headless Horseman…very cool. It was not crowded around City Hall, and a great view.
After the first parade, make your way around the stops…Fantasyland is the most crowded area - there is an outside dance party and the little kids just love it , but it makes that whole area very crowded. We dont have little bitty ones, so this was not a problem for us.
The fireworks are fantastic, as well, so dont miss them - nice to see and hear the music = we were near the speedway, behind the castle, not a bad view, great sound.
The candy rocks - we bring our special treat bags from home. You’ll never get this good chocolate on the streets on 10/31!
Whether you dress up fully - we were all pirates last year, or just wear the t-shirts, definately get into the spirit, it is a fantastic time! Enjoy - we’ll be going for our 3rd time this Sept.!
