Hi Tina,
Welcome to the Disney Parks Moms Panel and thank you for asking us a question!
I wouldn’t recommend experiencing
Disney’s Spirit of Aloha Dinner Show on the same night as you plan to attend
Mickey’s Not-So-Scary Halloween Party. There is so much to see and do at the Party that you don’t want to miss a second of it! Plus, your Party Ticket should allow you to enter Magic Kingdom Park as of 4:00 p.m., which means that you would be losing some hours of admission to which you would be entitled.
If you can move your dining reservations, I would recommend doing so. If you have to choose between Disney’s Spirit of Aloha Dinner Show and Mickey’s Not-So-Scary Halloween Party, I would definitely recommend the Party, especially because you’ve never experienced it before! I always recommend attending seasonal events, especially those at Magic Kingdom Park, because of how much fun they are!
Please don’t hesitate to come back and see us if you have any other questions.
Have a Magical Day,
Lynne
