Welcome to planDisney, Krystle!
A November trip to The Most Magical Place on Earth sounds wonderful. The Holiday decorations start to go up in those first two weeks of November. I'm sure your visit will be a "practically perfect" way to get in the Christmas spirit.
Krystle,
Magic Kingdom Park currently has a nighttime spectacular every evening, unless there is a special event that requires the park to close early.
Disney Enchantment is soon to be replaced with
Happily Ever After and I expect the latter show to still be around when you arrive.
Around the time of your visit,
Mickey's Very Merry Christmas Party runs on select nights at Magic Kingdom Park. This is a special event and therefore requires a separate ticket. It begins at 7:00 PM, but Guests attending this event are allowed into the park from 4:00 PM. Those with only a
standard ticket must exit Magic Kingdom Park at 6:00 PM. On these nights, there is a special nighttime spectacular, namely, Minnie’s Wonderful Christmastime Fireworks Show, for Guests attending Mickey's Very Merry Christmas Party. Therefore, the regular nighttime spectacular won't be shown on those nights. However, on any nights that don't have a special event you can expect to see the fireworks.
If you've never attended Mickey's Very Merry Christmas Party, I highly recommend it. It's a very unique and magical experience. Mickey’s Once Upon a Christmastime Parade is one of my favorite things at Walt Disney World Resort.
I hope that's helpful, Krystle! Have a great trip. Please come and see us again if you have any more questions.
Mike
