If you want to meet Jack and Sally, get in line as soon as possible. They always have the longest line and people start getting in line when they get in. The characters will take the longest time, so prioritize certain ones over others.
See the last showing of everything if you can. There are smaller crowds for Hocus Pocus and the parade at their last showing.
If you run out of room in your treat bag, you can ask for another and collect more candy!
The Cadaver Dans are not listed on the entertainment schedules. They can be found roaming Frontierland intermittently throughout the night.

Julia, I cannot emphasize this enough….if you want to see Jack and Sally, make that first priority. Get in line early, early, early. And when I say early, 4:30 is not too early. They will meet before the party and you do not want to be wasting an hour, hour and a half, two hours of party time in line for any character.
Prioritize the other characters you want to see. If you can grab a short line after Jack and Sally, get it. If not, sometimes end of night is shorter. Yes, they could be long.
Eat a good meal beforehand. Do not take time to eat a meal during the party if you can avoid it.
There are three rides with enhancements this year, Pirates, Space, Tea Cups. If you want to do those try to plan a time maybe during the first parade.
Keep an eye on the weather. If it looks dry definitely see the second parade. Far less crowded. Still, if you want curbside on Main Street you’re still going to have to stake out a spot early. Best parade on property in my opinion.
Trick or treating is not only fun, I highly recommend it. Where else can two adults such as yourselves trick or treat? We did two years ago, ages 51 and 50 and had a blast! If you are trick or treating early in the party and can, start back to front, far less crowded to start at the back.
There are some photopass shots only at the party. If you are interested in those plan some time.
Know and understand that you likely won’t be able to do it all. Prioritize so that you don’t miss any of your must do’s.

I hope this helps. Any other questions just ask! And above all, have fun with it! This is a great party where it doesn’t matter if your 5 or 100, it’s just so much fun to be a kid!

@Julie What day are you going to Mickey’s Halloween Party? If it’s the 3rd of September that’s where i’m heading. They have new additions and of coarse the candy..but i’m not going to give it away.
