Hi Jolene,
Thanks for stopping by the Disney Parks Moms Panel.
Mickey's Not-So-Scary Halloween Party is one of my family's favorite events at Walt Disney World. I think you are asking if the party is included in Magic Your Way tickets. The party is a separate ticket and therefore not covered by a regular park ticket. Party dates and ticket sales were announced in May last year so you might want to keep an eye on the
Disney Parks Blog this spring. There is usually a good discount for tickets bought in advance.
I recommend getting in the spirit of the evening with a costume, or a Halloween t-shirt if luggage space is tight! Do not miss Mickey's Boo-To-You Halloween parade and Happy Hallowishes fireworks. There are also dance parties and fantastic trick-or-treat trails.
If I misunderstood your question, or if you have other questions I can help you with, please let me know!
Wishing you a magical vacation,
Amy H.
