Hi, Adele!
Thanks so much for your kind words. I know that I speak for all of my fellow Moms and Dads here on the Disney Parks Moms Panel when I say that it is truly an honor to help Guests plan magical Disney vacations!
The "Unleash the Villains" Limited Time Magic event at Disney's Hollywood Studios will be held one night only: Friday, September 13th, from 8:00 PM to the 13th hour (1:00 AM). I'm sorry that you will miss the villainous takeover of the park, but if you're a Disney Villains fan, you can still mix and mingle with this fiendish lot at Mickey's Not-So-Scary Halloween Party (MNSSHP). This is a special seasonal event held in Magic Kingdom Park and it requires a separate ticket.
In addition to the Villains Dance Party (typically with appearances by Maleficent, Dr. Facilier, The Evil Queen, Captain Hook, The Queen of Hearts, Jafar, Cruella de Vil and Frollo), MNSSHP also features Mickey's Boo-to-You Parade, Happy HalloWishes fireworks, trick-or-treating in designated areas throughout Magic Kingdom and special Character meet-and-greet opportunities. MNSSHP is a must-do for my family every year -- we love dressing up in costumes and experiencing the spooktacular festivities!
During your visit (assuming a 5- or 6-night stay), MNSSHP is scheduled on the following evenings: Tuesday, 9/17 and Friday, 9/20.

Wishing you a
magical vacation! Please stop by the Moms Panel again with any additional questions as you continue planning your September visit.
