Hi, Nina! Guests are admitted until closing time, so normally you would have to decide how much time in the park would be necessary to make it worth using a day's worth of tickets. However, I checked the calender, and the Magic Kingdom closes at 7:00 P.M. on your arrival day. This is the first evening of
Mickey's Not-So-Scary Halloween Party. The Mickey's Not-So-Scary Halloween Party is a not-to-be-missed hard
ticket (requires a separate admission) event! The Magic Kingdom is
decked out in its Halloween finest - including ghosts on Main Street,
U.S.A. Characters sport their costumes, too. Guests of all ages attend
in costume, but it isn't required. Because the number of Guests is
limited, you can ride almost every attraction during the party time
frame, especially if you follow my family's lead and skip the
Trick-or-treat locations. HalloWishes is the holiday-themed fireworks
presentation that you can only see on party nights. The Boo-to-You
parade is one of my family's favorites. As in years past, there is
an advance purchase discount for many nights, including September 11, 2012.
If your heart is set on going to the Magic Kingdom on your first night, you will need party tickets. The party is from 7:00 P.M. until midnight! Happy planning and have a Magical vacation!
