Hi Danica! Welcome to planDisney.
Oh Boy! Fall is my favorite time at
Magic Kingdom Park. This pumpkin-spiced gal loves the theme- carved pumpkins throughout Main Street U.S.A. and fall foliage colors.
Mickey's Not So Scary Halloween Party is scheduled to begin at 7:00 PM. This means day guests without party tickets will be asked to exit the park at the official park closing time. Historically, this has been at 6:00 PM. You should plan on making your dining reservation at or before closing.
Here is my insider's tip as to why I like your plan. Many guests will not make a
Disney Park Pass Reservation on Mickey's Not-So-Scary Halloween Party dates because of the early closing. Last year, I enjoyed two such days without party tickets. I was able to do my wish list of attractions and sneak in some treats all before 3:00 PM. Personally, I think if you schedule an early evening dinner at the park closing, you will have a great Magic Kingdom Park day plan.
Alternatively, if you do decide to attend Mickey's Not-So-Scary Halloween Party, your party ticket allows entry into Magic Kingdom Park as early as 4:00 PM. With the party going on until midnight, you could choose a late afternoon to nighttime visit that would include trick-or-treating,
Disney's Not-So-Spooky Spectacular, and
Mickey's Boo-To-You Parade.
Keeping it Magical,
Cindy
