So if I'm already physically in magic kingdom, and MNSSHP starts why do I have to buy tickets for it. Do they close the park and kick everyone else out.
They do. It's a separate ticketed event.
You do not have to have a regular day ticket to attend, just the party tickets. You can enter the parks starting at 4pm with the party ticket but the festivities do not start until 7pm. At that time everyone without a party wristband will be asked to head toward the front of te park and leave.
The Halloween party includes;
-Special character meet n greets all over the park with tons of rare characters.
-special Halloween parade
-special Halloween wishes fireworks show
-several candy trails where kids can trick or treat and get lot of candy!!!
I am planning on doing the Halloween party next year, and this November we are doing the Xmas party.
For our trip in November we originally planned to do MK all day and then continue with the Xmas party, but opted to do MK our first day there, and then have a relaxing afternoon the day of the party, and go to MK at 4 when we can get in!
I would suggest doing something similar to that...this way you aren't wasting a full day ticket on essentially a half day at a park and paying extra to stay later.
Also the party goes until midnight!
