Just noticed you said you were planning on doing the soiree at one of them. If you are doing the early seating of the soiree and you can afford it, I would absolutely do 2 parties. One you focus on the soiree benefits- the parade, villians show, castle show, fireworks, and meeting the villians and enjoying the soiree. The second, you can see the other characters around the park, hit a dance party, get some hitchiking ghost and other pics around the haunted manion, enjoy the atmosphere, and do a little trick or treating. That is exactly what we are doing this year.
